Started basic playground for testing lexical as a new WYSIWYG editor.
Moved out tinymce to be under wysiwyg-tinymce instead so lexical is the
default, but TinyMce code remains.
To help override & gain control of setting text alignment in tables.
- Adds support of clearing "align" attributes in certain operations.
- Updates cell range action handling to dedupe execcommand handling.
- Adds clearing of additional alignment classes on direction control.
Closes#5011
Editor popup will now reflect the direction of the opened code block.
This also updates in-editor codemirror instances to correcly reflect/use
the direction if set on the inner code elem.
This also defaults new code blocks, when in RTL languages, to be started
in LTR, which can then be changed via in-editor direction controls if
needed. This is on the assumption that most code will be LTR (could not
find much examples of RTL code use).
Fixes#4943
- Prevented image toolbars showing for objects embeds due to tinymce
image placeholder, and added media toolbar.
- Fixed height of object embed placeholder being forced to auto
when in the editor, allowing height attributed to be properly
reflected as it would on normal page view.
Closes#4974
Seemed to be chrome specific from testing.
Required editors to have preventDefault called on dragover.
Tested in Chrome, FF, & Safari.
Tested in both editors, and re-tested text/image drop to ensure still
works.
Fixed#4975
Fixes custom table cell clear-format handling since it was being called
on many format removals, not just the clear-formatting action.
This updates the code to specifically run on the RemoveFormat action
which is triggered by the clear formatting button.
Fixes#4964
- Removes 'span' from being a valid part of alignment formats so it's
not used to align contents, since it's going to mostly be an inline
format, wheras you'd really want alignment on the parent block.
- Adds direction cleaning to all direction change events, to remove
direction styles and child direction controls which may complicate
matters and cause direction changes not to show.
- Makes text direction controls work with table cell range selections,
which TinyMCE does not consider by default, via manual handling.
