Broken generic default

[tien]

Encountered this weird bug where generic default got broken, but not when value is assigned to a var before being returned:

The typing of this particular case is rather complex, so I wanted to make sure that it's definitely bug before trying to create a minimum reproduction 🙏

There’s no shortcut to determining if this is a bug. The template is there to help the TS team triage and address issues. You need to fill out the bug template properly, including actual code and a description of the expected and actual results. Right now this is just some images from which very little can be discerned. If you leave it like this, it is quite likely that the issue will just be closed as unactionable.

There's nothing we can do with this. Please follow the template and provide a repro.
