Shrink Strip cross axis to content

[smessmer]

Is your feature request related to a problem? Please describe.
Using Strip is great for getting equal spacing along one axis (horizontal or vertical). This disables egui's default behavior of automatically sizing the widget based on its content. Unfortunately, it also disables that behavior for the other axis and uses up all the space. For example, when I want to equally space three cells horizontally, it will also use up all vertical space and layout any components following the strip below the visible screen area.

Describe the solution you'd like
A setting in Strip that constrains it to one axis, e.g. equally space three cells horizontally, but only take the vertical space used by the largest cell. Any content following the strip should be laid out right below the space needed for the largest cell.
