* MM-61894: keep markdown when pasting a copied message The paste handler only converted pasted HTML into markdown when it held a table or a link, so copying a rendered message out of a channel and pasting it dropped headings, lists, emphasis and code. It now converts any HTML that carries formatting markdown can express, and Turndown knows how to read back the markup Mattermost renders for code blocks, channel links and hashtags.

Size the fence from the longest run in the code.
