When trying to remove a format (bold, italic, underline), collapsed at
the start of the DOM, an error occurred because of a wrong range.
Ex.: `<p><b>Odoo</b></p>` -> when clicking before the word "Odoo", then
clicking the "bold" button, we expect to be able to start writing in
plain (not bold) text (for that, the DOM has to look like this:
`<p>\u200B<b>Odoo</b></p>`). We now have that proper behavior without
the accompanying error message and loss of selection.
