Is there any chance of getting this change accepted upstream? Getting patches into dotnet/wpf will let us eventually switch from a custom package to the in-the-box one, which could reduce long-term maintenance burden.

We would probably need to come up with a standalone repro for the crash, open an issue and a PR.

The build is probably failing because it was opened from a fork. If you pushed a branch to this repo, I'm guessing it would succeed. We don't need to do that to merge this, though.
