Using the following scene structure:

The SubViewportContainer with scale = 2:

Steps to reproduce

Put an OptionButton inside a SubViewportContainer hierarchy and set the scale of the SubViewportContainer to 2.

It seems the issue is with any transformation to the SubViewportContainer, not just scale. Even if scale is left at 1 but the container is translated, the popup remains in the original position.

I believe that #68627 will fix the position problem. Will test this later.

[Sauermann]

The combination of #66688, #68627 and #69185 will fix the wrong position. (Didn't expect it to be this complex)

The wrong popup-menu-scale is a different bug.

Will be fixed by #69185

[Sauermann]

#69185 will fix only one part of this issue. The problem of scaling was more complex and I don't have yet a complete solution available.

Tooltip popups are also affected.
