TinyMCE has a default entity_encoding 'named',
which causes text with diacritic symbols to be converted to HTML entities,
e.g. pâté will be convert to pâté
That will be a problem with the Glossary auto-linking filter if a course has a text concept like pâté,
then the filter will likely fail to get the text concept.
Changing the TinyMCE entity_encoding to 'raw' will resolve the problem.
Originally I changed the compiled output of TinyMCE from es2015 to es6
to try and allow our own requirejs system to serve the content.
This is a change in the TinyMCE repository (or our copy of it).
Unfortunately this turned out to not be possible, but I never got around
to updating the configuration to stop doing so.
Whilst working on this issue, I've removed this change to module
compilation, which brings us closer in line to Tiny core, and simplifies
the upgrade process.
This is in keeping with other Editors such as Atto and resolves an issue
where DOM Purification incorrectly identifies HTML-like string content
as an HTML tag with a JS variable.
Moodle already performs XSS sanitisation using HTML Purifier in PHP.
The boost theme makes the TinyMCE editor rendered in a scrollable container,
scrolling the editor’s container will cause TinyMCE UI elements to be detached from the anchor.
Therefore, to keep the tinyMCE menu in the correct position,
adjustments must be made on the page drawers style.
When using TinyMCE editor in Safari browsers, a problem may occur where the dialogue
windows (such as modal dialogs) overlap with page drawers due to a specific behavior
in Safari's rendering. This function addresses the issue by adjusting the CSS overflow
property of the page drawers, ensuring they do not obscure the dialogue windows.
Add code formatting (indenting) as well as code style (tag color)
via a TinyMC plugin. To make it easier to make code edits when
viewing the editor content in source code view.
From my experimentation I have discovered that Safari does not properly
respect the standard MediaRecorder mimetype. Instead of using `codecs=`
it uses `codecs:`.
This change copies the codec array to have the list of possible codecs
include both codecs= and codecs: whilst remaining in order.
