Picker value resets when in a sheet, but works fine in parent View

In the attached minimal reproducing app, the picker in the List works as expected while the one in the sheet resets every time the List view updates (this demo app displays a random byte value that is updated every second).

Can anyone explain why this happens and how to solve the issue, i.e. how can I have a picker in a sheet on a view without the picker getting reset when the parent view receives updates?

Somebody asked the same question here, but it is unanswered, it has different example code: https://www.hackingwithswift.com/forums/swiftui/picker-value-resets-when-in-a-sheet-but-works-fine-in-parent-view/17211
