Markdown block breaks for some syntax

[jaked]

MDX is pickier about syntax than GitHub-Flavored Markdown:

• it doesn't accept unclosed tags, so e.g. unclosed <img> tags are not supported (example, example)
• "Expected Unicode escape sequence \uXXXX" (example)

note: this is handled in the new Markdown-edit Block, and we might not need to tackle this if we're replacing the old Markdown Preview Block

[jaked]

huh does the new Markdown-edit block use something other than MDX to render pages? I would expect to see the same bug otherwise.

[Wattenberger]

it does! it's just CodeMirror with a bunch of custom plugins and a Markdown parser

[jaked]

whoa! gotta read that code

Not sure if it's the same issue or not, but noted the tables in the examples repo weren't rendering properly in blocks, but were in the normal site.
