"Microsoft Sans Serif" alternative font metrics are incompatible with original font

[w-flo]

Game: ZUSI 3 - Aerosoft Edition (1040730)
Affected Proton version: 6.3-8
Not affected: 5.13-6

The font added in ca928d3 as a "Microsoft Sans Serif" alternative appears to have a slightly larger line height compared to the original font.

This causes the "ZusiDisplay" application which is bundled with the game "ZUSI 3 - Aerosoft Edition" (1040730) to have an unusable settings menu. Since all the form elements in the settings are a bit larger because of the font height, the "Speichern" (save) button at the bottom of the window is outside of the visible region of the window. The window is not resizable, so there is no way to save the settings.

This is not an issue with Proton 5.13-6 (which doesn't ship a micross.ttf replacement, but somehow the application now handles this gracefully since the latest application update yesterday, so the menu works - maybe falling back to Arial), but it is an issue with Proton 6.3-8. So it's a regression.

Steps to reproduce:

1. Launch the Zusi 3 game from Steam (on first start, may need to select a language in the first start wizard, assuming Deutsch/German here)
2. In the window menu, select "Konfiguration" -> "ZusiDisplay starten" -> "ZusiDisplay Grundmaske starten".
3. Wait for ZusiDisplay to launch
4. Click the cogwheel icon in the top right corner to open the settings menu
5. Notice the buttons at the bottom of the settings menu are cut off, so there is no way to save any changes

If ZusiDisplay crashes on start while trying to reproduce, it might be due to this crash that depends on a race condition: ValveSoftware/wine#132 I'm using a patched uiautomationcore.dll for Proton 6.3 with the upstream patch applied, which reliably fixes it for me. Sometimes it works using unpatched Proton 6.3, so who knows what it really depends on. Maybe disk access speed / file caches.

Edit: The patch is part of Proton 7.0 so it should just work.
