Editing a table with firefox breaks editing when double clicking + paste (ctrl+v/cmd+v) a text in the table

Steps to Replicate

1. Add a table in a page
2. Copy a text, double-click inside a cell and paste the content

Expected Results

Content is pasted

Actual Results

Content is pasted outside the table, removes the cell and breaks the editor by not allowing any other action aside from Update/Close. Check: Recording #1.mp4

Workaround

Affects only Firefox.
Don't double click and paste a content inside a table cell
