 For #28874 I tried to create a debug build for Windows in order to get
 more information from a user on what is going on on their machine. While
 testing the debug build myself it turns out it crashes in different ways
 when running, making this approach of debugging #28874 unusable. On first
 start it crashes with:
 {{{

 On subsequent starts I only hit the `MOZ_CRASH` in the above output but
 the browser is unusable:
