Editing a long message does not change HTML

[link2xt]

If the message is short, and then you edit it to be long, the text is replaced but no HTML preview is created. This is a minor bug, because normally if the message was short, it stays somewhat short after edit even if a few sentences are added.

If the message is already long and has a "Show Full Message..." HTML part, the behavior is clearly buggy. When you click "edit message", [...] is part of the text that is editable. And after editing, HTML preview is not updated, so it contains old text.

maybe not allow editing messages that have an html part.

usually, they are not created by normal typing, so out of scope of typo fixing and editing, similar to images
