Sets sizes on WYSIWYG code block sections based on content lines
as an early pre-codemirror height prediction to avoid excessive
jumping in the editor.
For #3326
This filters out <br> elements within code blocks and replaces them with
newlines. The editor started using <br>'s more harshley after some
configuration changes upon upgrading tinymce, in which we standardised
on forced br tags to avoid empty elements.
For #3327
- Updated styles to better align checkboxes within page content.
- Updated functionality to use a cross-compatible property on checkbox
click within the editor.
- For some reason, TinyMCE would handle empty paragraphs with a ' '
by default but this would be removed when the paragraph had an
attribute. This was fine in the old editor.
- This changes the approach to use '<br>' tags within elements
for "spaced emptiness".
- For compatbility with any existing empty paragraphs, I updated the
styles to show default height for empty paragraph sections.
- This also makes changes to help preserve encoded html tags
since they were getting converted along the journey.
Related to #3302
- Allows for easy unlinking, link preview or link editing.
- Created custom one to limit actions available.
- Performed refactoring of non-plugin toolbar editor code to extact into
its own file.
Related to #3276
- Fixed issues with new code blocks breaking or acting odd due to
misnamed contenteditable attribute.
- Helped fix issue where code blocks may show in a strage blank state
due to timing within shadow dom loading.
- Fixed some function timing issues where some functions required their
async predecessor to have finished.
Tested rather heavily in firefox and brave.
Fixes#3292
Code blocks in tinymce could sometimes end up exploded into the sub
elements of the codemirror display.
This changes the strategy to render codemirror within the shadow dom of
a custom element while preserving the normal pre/code DOM structure.
Still a little instability when moving/adding code blocks within details
blocks but much harder to break things now.
- Ensures padding works across FF & Chrome, was only working on FF
before.
- Fixes sketchy editor positioning focus on FF, since tinyMCE would
add a hidden element to the bottom of the body which would remove/add
our body padding causing unstable positioning.
- Removed old 'editor-*-update' commands to instead use the aligned
'editor::replace' command that we already have.
- Changed the way custom styles are loaded for the WYSIWYG editor so we
don't need an API call but instead scape content from the parent page
header using comments as identifiers. Added tests to ensure comments
exist and align.
- To display license info along with shortcuts.
- Extracted out plain layout from 503 error page.
- Added tests to ensure license references are as expected.
- Split everything into specific plugin/concern files to make things
more managable. Means original component file is now simple and much
of the core config is focused in one place.
