explorerframe:nstc - test_events() sometimes gets unexpected events on Windows
7. This can either be a single event but it can also happen multiple times for
multiple events:

nstc.c:2265: Test failed: Got event 4, count 1

or

nstc.c:1906: Test failed: Got event 7, count 0
nstc.c:1908: Test failed: Got event 4, count 0
nstc.c:1912: Test failed: Got event 4, count 1
nstc.c:1912: Test failed: Got event 7, count 1
nstc.c:1912: Test failed: Got event 12, count 8

This first happened on 2022-12-07 and has been happening roughly once every
three week since. So it's probably caused by a commit in the fall of 2022.
