Hmm, I could do a semi-permanent workaround in Xmir along the lines of:
Xmir -flattenOverrideRedirects
That might be adequate to fix this for Firefox and others. Although I dread having to make Xmir lookup a blacklist of broken apps and apply workarounds on the fly. It would be better in the long run to fix the Mir architecture (separate on-top from keyboard focus).
