Backport of #39774 and #39856 to the
release/5.0-preview8branch.Fixes #39473 (Tests failed on WASM with NRE in CustomAttributeTypedArgument.CanonicalizeValue)
Description
Fixes an issue where the Mono runtime/GC wasn't correctly tracking newly created objects when creating a custom attribute type. This resulted in rare and random
NullReferenceException's during the dotnet/runtime libraries tests. We also got one report from Blazor that looks like the same thing.Customer Impact
Random
NullReferenceExceptionwhen creating custom attribute instances.Risk
Low, we ran several libraries tests in a loop for multiple hours to confirm the issue was fixed.
