Thanks for trying it out. Sorry about missing your first patch: 
apparently while it was the first time-wise, it was help up in moderation.

Anyway, you make a good point about the case with the regexp: since I 
matched the pattern inside, the bounds of the node are off by one 
compared to the case with the jsx node. Your patch moves those bounds, 
but then they'll be wrong for the latter case.

Here's an update which tries to handle both, but I guess if we add more 
node types later we'll just have to stop trying to handle them the same 
way (and do it closer to ruby-ts--syntax-propertize).

Also added the new return_statement case for jsx.
