This isn't 100% reproducible, but I can usually get it to happen with the following steps:
1. click into a textarea (add comment field on this page), or editable html region (gmail)
2. type the following: The quick brown foxxx jumped over
3. hit the back arrow four times to move the cursor to the beginning of 'over'
4. hit return
The red squiggle under foxxx will disappear.
I haven't tried on mac, just windows.

A Quick Fix
I accidentally noticed a cause of this bug while investigating another issue.
Somehow the InsertLineBreakCommand::doApply() function forgot copying markers while splitting a text node with a line-break key even though there is a CompositeEditCommand::splitTextNode() function, which splits a text node and copy markers.
I'm not sure it is correct to call the CompositeEditCommand::splitTextNode() function here, though.

so, deleteTextFromNode removes spelling markers from text even if the deletion doesn't effect them? we should document that problem.
do we need to make this change to InsertParagraphSeparatorCommand and BreakBlockquoteCommand?

Oops my mistake, I misread the code, I thought it deleted what was after the caret, not what was before. Disregard that bit.
Thank you for your review and comments.

As far as I read the InsertParagraphSeparatorCommand::doApply() and BreakBlockquoteCommand::doApply() functions, they already use the splitTextNode() function to split a text node. (This is a reason why my quick fix uses the splitTextNode() function.)
