_content/js: make tab on selection undoable

People often highlight a selection and type tab, hoping to indent it.
Instead, the editor replaces it with a tab. That's fine - some editors work that way.
But the old implementation did not push that edit onto the undo stack,
so that there was no way to get the deleted selection back. Fix that.

Fixes golang/go#41037.
