Definition lists confuse the editor in Firefox

Pasting from a definition list into the editor makes it all confused. There's no way to start a new paragraph afterwards.

Create a standalone document:

<dl>
<dt>Term</dt>
<dd>Definition</dd>
</dl>

Select-all and copy. Create a new page and start a block quote with 'bq.'. Paste in the dl.

Note that the cursor is at the end of 'Definition'. Hit return and notice that the cursor has added a new line in the definition but not broken out of it into a new paragraph, nor ended the block quote.

I would expect it to behave like a regular paragraph in a block quote, where hitting return on a final blank line breaks out of the block.
