Bug ID: 51477
           Summary: user32:input test_Input_blackbox() gets unexpected
                    00&41(A) keystate changes
           Product: Wine
           Version: 6.10
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: user32

test_Input_blackbox() gets unexpected 00&41(A) keystate changes:

https://test.winehq.org/data/patterns.html#user32:input

input.c:757: Test failed:  0 (a4/0): 00 from 00 -> 81 unexpected
input.c:757: Test failed:  0 (a4/0): 41 from 00 -> 01 unexpected

* This exclusively happens for the first sendinput_test entry which is supposed
to simulate pressing the left Alt key (VK_LMENU == 0xa1).
* I do not know what the 00 virtual key code corresponds to. According to the
failure message this key is getting pressed down and toggled.
* The 41 virtual key code should be the 'A' key but that's not a toggle key
(unlike, e.g., Caps Lock) so the low order bit should be meaningless. So it's
strange that it changed from off to toggled.

* These failures happen on the following machines:
  (41 corresponds to 100% reproducible, some machines may have fewer than 41
runs)

--- Comment #1 from François Gouget  ---
This failure happened on Windows 11 from 2022-09-26 (when that VM was created)
to 2022-11-01 (when the snapshot was updated to fix a Windows update issue).
But that stopped.

So now this failure only happens on w7u. It has a variant that does not seem to
ever happen during the WineTest runs but which did happen during MR!1619
(2022-12-01):

input.c:748: Test failed:  0 (a4/0): 00 from 00 -> 80 unexpected
input.c:748: Test failed:  0 (a4/0): 41 from 01 -> 00 unexpected

Should be fixed after 998003bda16a52cd834869f9a0e987438a130849 which refactored
the test logic.
