Document display and document editing are rather different tasks. The DOM was built for the display of static documents. Dynamism was slowly added over the years through JS, and eventually CSS (animations, transformations, etc). But the underlying purpose of the browser rendering engine has remained the same, which is to display static documents. It's not surprising that a client built from the ground up around the concept of displaying static documents doesn't do a good job of allowing users to edit documents in a WYSIWYG kind of way. That has never been its job!
