Block node commands misbehaving inside nested block nodes #38
Description
Reported on Meta.SE
Describe the bug
In Rich Text mode, type some text, click the Blockquote button, then click Bulleted list:
Now when I click the Blockquote button again, I expect the blockquote to disappear (the gray outline indicates it's some kind of toggle, right)? Nope, it's the bulleted list that disappears:
(In Markdown mode, the bulleted list replaces the blockquote formatting, which is OK behaviour IMHO; especially, the buttons don't have a gray outline.)
