[FIX] web_editor: translatable after pasted translation

Fixes same issue as b836e00d but for `<div/>` tag.

When we translate html content, all text and (currently) this subset of
inline tags are allowed inside translations: 'abbr', 'b', 'bdi', 'bdo',
'br', 'cite', 'code', 'data', 'del', 'dfn', 'em', 'font', 'i', 'ins',
'kbd', 'keygen', 'mark', 'math', 'meter', 'output', 'progress', 'q',
'ruby', 's', 'samp', 'small', 'span', 'strong', 'sub', 'sup', 'time',
'u', 'var', 'wbr', 'text'.

In b836e00d an issue was fixed that `<p/>` would possibly get inside
translation when copy-pasting, testing some scenario in current chromium
browser (83.0) it seems the pasted content contains `<div/>` tags.
