In the past, this worked fine, right now I can't compare with ffmpeg (where it 
also doesn't work afaics - it worked at some point).

You would see that behavior if you didn't configure with 
'--enable-vp9-highbitdepth'.
vp93-2-20-10bit-yuv440.webm seems all right.

high bitdepth unit tests (including the test vectors) should run nightly:

Hm, you're probably right, but why does 422/444 decode without error then? I'd 
expect all of them to error out saying "unsupported profile".

yes that would be unexpected; I'm not sure what the distinction is currently.
