Regarding the selection normalization, I believe, the idea is that
when selection is on contenteditable=typing, browsers do new behavior,
while otherwise legacy behavior.

Since execCommand() involves selection normalizations, making it to
work well against the new normalization behavior is not easy. I would
prefer execCommand() simply fails if the selection contains
contenteditable=typing, and editors do all the work with intentions
and possibly with DOM manipulations.

What do you think?
