Because screen readers don't know that the anchor icon is not meant to be read,
they might read the title (which is the same as the heading itself) in addition
to the heading, thus causing a duplicated output.

In e17cc644 the Webpack build process for CodeMirror was changed.
For unknown reasons, not all plugins and modes were added.
This adds all plugins currently enabled in

The snippet export broke due to two reasons.
First of all, the request to GitLab fail in the
default configuration due to the CSP not being
set properly. This commit adds the configured
GitLab base url to the connect-src directives.
The second problem is a change in the GitLab API
spec. Instead of `code` and `file_name` the
GitLab API now requires an `files` array with
`content` and `file_path` entries per snippet.

The hex2rgb function seems to previously have been available globally.
It probably got lost in the great Webpack refactoring and nobody noticed
that.
This copies the function into its own file (to make importing it easy)
and adds an import in index.js.

Previously, the HTML export template `html.hbs` included CDN links
for the HTML and CSS resources.
This commit enables Webpack to create a new `htmlexport.html` at
build-time, which includes all resources inline.
That template is then used as before by the frontend to be populated
with the rendered note content.
The tradeoff is that each exported .html file is about 5.6 MB in size,
as we need to inline all fonts (icons & emojis).

This adds the secure flag to all cookies that are set
in the frontend for storing various settings.
If `SameSite=none` is set (like when embedding the instance is allowed),
the `secure` flag is necessary to set any cookie.

This commit moves the import of highlight.js into a `require.ensure`
block, that is only executed when a code-block is actually present
in a note. Webpack automatically splits the library into a separate
chunk and loads that on demand.
The call to `hljs.listLanguages()` in `index.js` is also replaced
by a static list. This is important, as `index.js` would otherwise
need to import highlight.js, which would cause the quite big
library to be included into nearly every entrypoint, needlessly
increasing the transferred code size.

This commit moves the import of viz.js into a `require.ensure` block,
that is only executed when a graphviz diagram is actually present
in a note. Webpack automatically splits the library into a separate
chunk and loads that on demand.
To ensure that graphviz code-blocks are not treated as normal
code-blocks while the chunk is loading, a corresponding check is added
to `finishView`.
The library is also removed from the Webpack config file, as it only
is used at one place in extra.js, which is handled by Webpack
without any extra config.

The html.hbs template does not contain any logic,
so we can replace the lib with good old string.replace calls.
This significantly reduces the bundle size, as we don't have to ship
a full template engine to the client.

The ot library is tricky to load with Webpack, as it writes
it's functions into a global `ot` object and does not export anything.
I got it working using `exports-loader` to put the `ot` object
into a CommonJS export and then forcing Webpack to only
load using CommonJS.

A bug in insertOnStartOfLines lead to duplicated text,
if the cursor was not at the start of a line.
This fixes the behaviour of insertOnStartOfLines to always use
the complete first and last line of the selection,
even if they were only partially selected.

jQuery's .html() method escapes contained text (e.g. '<' becomes
'<'). This confuses the turndown parser, which then only performs
unescaping, but does not convert to markdown.
By using .text() instead, the unescaped content is returned and turndown
can correctly generate markdown.

Reveal.js doesn't set the default value of an option in the provided config object
if the key is set with "undefined" as value. This leads to a broken slide mode,

This should prevent the issue mentioned in https://github.com/hackmdio/codimd/issues/1648
Specifically left out are
- dependency (user can't really include anything anyway, because CSP forbids most domains)
- autoSlideMethod (nothing our users should be able to change as they won't write JS to be affected by this)
- keyboard (this let's users write arbitrary code and seems therefore to problematic)

Using jQuery's `.html()` method stores the given string as `innerHTML`, which enables injection of arbitrary DOM elements.
Using `.text()` instead mitigates this issue.
