Always report both finger between the sync. Even if the documentation

I have a similar patch to address this issue. Would you please try to
see if https://bugzilla.kernel.org/attachment.cgi?id=73991 works for you?
Ignore the duplicate or release events. They keep some gestures from
working (such as the two-finger tap)
This seems to fix the problems reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=43591
FWIW, https://bugzilla.kernel.org/show_bug.cgi?id=43197 is the original
thread of the aforementioned patch.
Thanks,
