WinUI3: Combining ViewBox and Grid

[BarneyHoundDog]

Hi

I have a simple grid with two columns that take 50% each of the available width. No matter what the content of each column the 50% width is respected.

If wrap the grid in a Viewbox so that it scales the width of the two columsn becomes dependant on the content. This seems wrong - or have I misunderstood the purpose of a Viewbox? Is there any way to control this behaviour?

It is different for me with or without ViewBox.
