Hi
Using WordPress 5.7.8 (but also all other more recent branches) - characters are stripped through TinyMCE Copy paste from Word.

Under conditions: Bulleted list, from word, pasted, containing a dot at the end of the word.
Detailed descpription with fix here:
​https://github.com/tinymce/tinymce/issues/3480
​https://github.com/aautio/tinymce/commit/b5f4db5a8377d2beb9ca3a1a7164587b280acbf4

Seems implemented in TinyMCE since March 31 2021, however the update of TinyMCE editor has not yet been included in current WordPress versions.

Can this still be applied?
Kind regards,
