DeferredImageDecoderTest.decodedSize is the test that is failing.

Findit found https://chromium-review.googlesource.com/c/chromium/src/+/1185629 to be the suspected cl, however reverting it has a merge conflict, and https://chromium-review.googlesource.com/c/chromium/src/+/1185793 seems related too.

khushalsagar@ please revert the related cl(s) or land a fix.

I'm looking into this now.

How close are we to a fix? Should we just disable the failing test in the meantime?

Fix up: https://chromium-review.googlesource.com/c/chromium/src/+/1188877

And its in the CQ now.

blink: Use external memory allocator in tests using MockImageDecoder.

The caller expects the decoder to populate memory in the allocator if
set, but the MockImageDecoder was not doing this. This causes failures
in MSAN where the memory remains unitinitialized.

Fix MockImageDecoder to respect this expectation.
