Does this address #4116?

nojnhuh

I think this is correct. Could you please fix up this PR to be more descriptive and add tests? e2e tests might also need to be updated.

nawazkh · 2023-10-12T17:55:51Z

Thanks, Jon!
I am trying to reproduce this, will fix up the description and add tests after that.
I think Jack has an improvement to build upon: #4124

nawazkh · 2023-10-12T22:23:44Z

Converted to draft so that I don't trigger any more tests on an in progress PR.

@nawazkh Are we sure this bug affects 1.10? Or do we know that this isn't related to the SDK v2 migration?

Are we sure this bug affects 1.10? Or do we know that this isn't related to the SDK v2 migration?

Confirming. Will update in a bit.
