Convert divs when cloze deleting?

The issue mentioned on https://github.com/ijgnd/anki__editor__apply__font_color__background_color__custom_class__custom_style/issues/45 also affects cloze deletions made across multiple divs - they end up having extra lines inserted, and don't display properly during review, as the subsequent text manipulation creates invalid HTML.

While the new editor code should use `
`s when typing in, a lot of users paste in content from other sources. I wonder if we could make the cloze deletion action handle this? If it detected a selection across multiple nodes, maybe it could automatically convert the nodes covered by the selection into linebreaks instead? Or maybe this would cause more problems than it would fix?
