That's true, and I've been working on a patch to make that behavior
more robust. The code for that is in
`python-electric-pair-string-delimiter', but I think an improved
implementation of that would depend on how this bug is fixed. I have a
local patch that works for me, but it depends on the other
electric-pair settings I use, so it couldn't merge as-is.

In particular, it would need to take into account the various possible
settings for `electric-pair-skip-self', since with that set to nil,
I'd generally expect `python-electric-pair-string-delimiter' to be a
no-op (we should already have three quote characters after point, so
no need to insert more).
