Bug ID: 58810
           Summary: Steam: Unable to display the intended GUI windows due
                    to steamwebhelper being unresponsive.
           Product: Wine
           Version: 10.16

After 2a2cc34db71 [1], Steam appears to launch, showing its notification area
icon, but no window will appear.

After a while from clicking said icon, the "Steamwebhelper is not responding"
window [2] will appear, with a few different options to restart things with, of
which none do any better.

I believe the

src\vgui2\vgui_surfacelib\Win32Font.cpp (963) : Couldn't get string length

line shows up only when this problem can be seen, which could be a sort of a
hint at least.

Building before the mentioned commit, or reverting it, and efce37afd70 due to
conflicts, on current 'git master' will make it work again.

Hacking on it a bit, removing the 'wcsupr(refkey->name);' line also makes it
work, though maybe that is obvious in this case, and might more or less nullify
the point of the uppercasing intended.

(Did not try a fresh prefix and clean install of Steam yet due to the
cumbersome log-in process, but hopefully that is not necessary here.)

Last tested at 'wine-10.17'.

Thank you!
