Thanks, but why do you expect "(())" rather than "()()"?  Electric
Pair mode works per inserted character, and doesn't know anything
about nesting.

In any case, this should have been submitted as a bug report, and go
to the bug tracker, not posted here.

I noticed the unexpected behavior when attempting to surround some text
with multiple braces in order to create Anki flashcards.

More or less, I wanted to go from "foo" to "{{foo}}", and I thought
perhaps that with the whole word selected, pressing "C-2 {" would DTRT.

In general, I'm not sure whether "{}{}" or "{{}}"is more useful or
expected, but I suspect both are better than "{{}".

You're right.  I'll repost on the bug tracker.

Thank you!
