Cannot get working in chrome reliably due to conflicting handling of
events and drag+drop API. Getting attachment drop working breaks other
parts of TinyMCE.
Implementing current work as should still work for MD editor and within
FireFox.
Related to #1460
- Will focus on title if the value of the field matches the default text
for the current user's language.
- Otherwise will focus on the editor body.
- Added and tested on both editors.
For #2036
- Updated editor, and other area, styles to look okay in dark mode.
- Used tinyMCE theme generator to create dark mode theme.
- Updated tinymce to latest 4x version.
- Allowed DRAWIO env option to be passed as URL to point to instance.
- Updated tests to check URL gets passed to pages correctly.
- Update default URL to be the default theme.
For #826
- Extracted logic to get images from paste/drop event into own file to
align usage in both events for both editors.
- Fixed non-ability to drag+drop into WYSIWYG editor.
- Updated check for table data to look for table specific rich-text
instead of just any text since some the old check was too general and
was preventing some legitimate image paste events.
Tested on Chrome and FireFox on Ubuntu.
Attempted to test on Safari via browserstack but environment was
unreliable and could not access folders to test drag/drop of files.
