Hi Israel,

Good to hear from you.  We had a lot of changes in 0.12.3 (one day we'll do
a release with only a few changes), but I can't think of anything that
would have broken mouse behavior.

That said, just yesterday, I did merge an issue that does effect zooming,
the issue was noticeable when the grid was displayed; but the issue it
addresses is/was quite old.  If you can, I would try and give `master`
branch a chance, otherwise, if a minimum reproducible example is out of the
question, I would attempt to do some kind of git bisect and see if you can
zero in on the commit that started causing the problem to begin with.
