I see that the unit tests fails on a couple platforms (although mac failure looks like a network problem with the GitHub actions server). Since you are several commits out of date, can you merge in the latest changes from upstream master into your branch?

And speaking of tests, can you create an automated unit test to verify this fix?

I presume you've tested this with normal sized tooltips. Have you found any differences in behavior in those cases with the added event filtering?

I also left one more formatting comment below.
