Any update regarding the regression range?

I have 2 regression ranges here:

- first regression range is for the case when Menu Bar isn't visible with High Contrast White Theme -> here is the pushlog URL: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=bbc9b2b50815f2d48492c0b5434804605438b9a0&tochange=f605d6efe3476538613b0fcca7d2582c2a3606cc

I think that bug 1437052 is causing the problem. 

- second regression range is for the case when Menu Bar is visible, but the tabs name aren't visible (with High Contrast White Theme); it seems that this issue (that the tabs name isn't visible) appeared in build when Title Bar was included in "Customize" -> here is the pushlog: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=73eefb421e2a&tochange=d09f9a9f81ae

> Windows 10 is affected too.

Alas, Windows 8.1 and 10 don't share the responsible theme code. And since I can't currently test on 8.1, I'll only take care of Windows 10 here.

With the native title bar enabled, stop using -moz-win-glass on Windows 10 / high contrast. r=Felipe
