bullseye libgtk-3-0_3.24.24-4+rpt3 breaks touch events

[wellenvogel]

Describe the bug

With libgtk-3-0_3.24.24-4+rpt3 touch events from an ILITEK ILITEK-TP stop working.
Initially I encountered the problem with firefox not handling touch scroll any more.
Finally I went down to a small python test prog (attached) that should show the touch events.
I did some further testing and found that it still works with libgtk-3-0_3.24.24-4+rpt2.
So from looking at the patches it seems to me that doubleclick.patch breaks the correct handling of touch events.
touchtest.py.txt

Steps to reproduce the behaviour

Use the attached testprog (needs python3-gi installed) and touch the area. Should report touch events and button clicks.
In the error case it only reports button events.
