[BrzVlad]

#80186 fixes a regression from the same commit reported in the microbenchmarks.

Are all tests still enabled so we can see if that PR is also a fix for this ?

[radical]

We run only System.Runtime.Tests+AOT on PRs by default. Use /azp run runtime-wasm-libtests to run all the library tests with AOT.

[BrzVlad]

This failure was fully deterministic ?

[radical]

We have been hitting it on every rolling build, AFAICS.
