[WinCairo][WK1] A browser window starts as an inactive window because AcceleratedCompositingContext::acceleratedCompositingAvailable creates temporary window MiniBrowser.exe --wk1 starts MiniBrowser as a inactive window.
Per, can I revert your r179962?

(In reply to Fujii Hironori from comment #1) > Per, can I revert your r179962? I think I would prefer to keep it, since there will be no drawing without it when accelerated compositing is not available. Maybe the temporary window could be created with a different style? From the current style, it seems it won't get activated.
I found a serious issue of AcceleratedCompositingContext::acceleratedCompositingAvailable on Windows 10 version 1809 or newer (Bug 200563). I can't find a solution for both issues (Bug 200563 and Bug 200493). Let's revert it until someone wants to solve these issues and the original issue (Bug 140667).
