If this is really a font bug, then we should ask Apostolos to fix Asana
Math, we can try to patch Cambria at run time, but the less font
patching the better we are.

I think it might be an engine issue, I recall having the same problem
with Neo Euler until I disable the extensible integrals (I think other
fonts have no extensible integrals so the issue is hidden).

I think those two issues should be directed to TeXLive team.
