Date picker: Selecting day in next month fails sometimes #2247
Description
Describe the bug
This seems to be another firefox specific issue.
Sometimes when i click on a day in the next month, the value of the DatePicker isn't updated. Inspecting the value shows that there are 2 updates: first the date gets correctly set, then it gets set to undefined.
Maybe it has something todo with the mouse event issues i reported here
DatePicker2.mp4
Reproduction
You can reproduce it with this repo (atleast in Firefox).
It might take a while to reproduce it. I couldn't figure out what conditions reproduce it a 100%.
