Formatting was not persisted on empty paragraphs, and was instead based
upon last format encountered in selection.
This was due to overly-hasty removal of other formatting code, which
this got caught it.
Restored required parts from prior codebase.
Also updated inline format button active indicator to reflect formats
using the above, so correct buttons are shown as active even when just
in an empty paragraph.
- Fixed new code block insertion to remove selection area instead of
just adding after.
- Added default table column widths to not be collapsed
- Updated table dom export to not duplicate colgroups.
Added list nesting support to allow li > ul style nesting which lexical
didn't do by default.
Adds tab handling for inset/outset controls.
Will be a range of edge-case bugs to squash during testing.
Changed from using a decorator to using a helper that watches for image
selections to then display a resize helper.
Also changes resizer to use a ghost and apply changes on end instead of
continuosly during resize.
