Based on the test.winehq.org history these tests started failing on the 
26th of December:

  https://test.winehq.org/data/tests/dinput:mouse.html


A bisect shows they are caused by this commit:

    winex11.drv: Send HTMENU instead of HTCAPTION to query window activation.
    
    Commit 71d35d8940118bc6de6522913fb8c473fa5b2c24 broke the way
    WM_TAKE_FOCUS protocol is implemented: WM_MOUSEACTIVATE now replies
    MA_NOACTIVATE by default when using HTCAPTION.
    
    We use the WM_MOUSEACTIVATE -although Windows does not- regardless of
    the way focus is changed to check whether a window wants focus, and
    Windows sometimes changes focus regardless of the message reply.
    
    Steam and the Wine system tray are affected for instance.

There are actually two versions of this patch on the mailing list:

* https://www.winehq.org/pipermail/wine-devel/2019-December/157117.html
  - Modifies dinput:mouse, marking the failing tests as todo_wine. So 
    the TestBot found that dinput:mouse succeeded, although with todos:
    https://testbot.winehq.org/JobDetails.pl?Key=62569

* https://www.winehq.org/pipermail/wine-devel/2019-December/157099.html
  - Only modifies winex11.drv. Because of that the dinput:mouse test 
    was not run and the regression was not detected by the TestBot:
    https://testbot.winehq.org/JobDetails.pl?Key=62502
  - Posted a couple of days before the version above, this is the 
    version that got committed.


So the patch was known to to cause these failures and presumably that's 
being worked on (if not it would be good to make a bug report for 
reference).
