[BUG] numbering append with <ol> when the last item deleted

[donynuransyah]

Thank you a ton for your hard work in this library.
I just want to report some issue with the numbering format it's got append with <ol> when I tried to delete the last item, but when I delete it again the <ol> tag disappears.
but if under the numbering we have some words the bug didn't happen.
i thought it had something to do with getAbsoluteIndent or getRelativeIndent
here is the video I tried to reproduce.

This is a known issue but I haven't found a solution yet. It makes sense to delete the last OL because otherwise it would be impossible to go from Ol to regular text (except by clicking the button/icon but that's cumbersome). There are alternative ways like deleting the OL when the user hit the return key (like this Github editor does). The behavior with a regular line of text below (second video) should be consistent though (which it's not).
