Hi @twkrol @Archmonger, What is the status of this PR? Why is the status in the draft?

[twkrol]

Hey, I would love to merge this feature, but need help to make tests. Anyone?

[Archmonger]

@angryfoxx Tests are still needed for this PR.

On top of that, there's a more pressing issue that blocks all PRs from being merged #483

[angryfoxx]

Hi again @Archmonger, is that issue still persisting? I can write test and update this pr if there is no blocker.

[Archmonger]

Yes.

@johnthagen has created a workaround for our broken workflows. PRs are now mergeable again.

[johnthagen]

@angryfoxx Please resolve merge conflicts and merge main in your branch for CI to run properly.

[angryfoxx]

Hi again guys @Archmonger @johnthagen. I have created pr about that issue and could you review it ?
#507

[Archmonger]

Closing this in favor of #507
