The first one is fixed on latest core/persona/vanilla.
Second one I'm not sure about, looks like a templates.js bug.
Made an issue.
@psychobunny fixed it in templates.js, updated this forum as well.
The problem maybe i can't activate 'Allow HTML' in Markdown Plugin Settings.
Save Settings button not working and I don't know why!
