Findit cannot find any culprit results.

using codesearch, seeing some changes to 'IntermTraverse.cpp' in
https://chromium.googlesource.com/angle/angle.git/+/1ecd14b875f110b9c94c2dc34c219fb3267ee51a

No repro on latest Chromium. This ANGLE change fixes the issue: https://chromium-review.googlesource.com/c/431001/

If this bug is against an older branch, the fix should be cherry-picked there.
