Manipulating `Adornment` doesn't always cause `LayoutSubviews`

[tig]

Oh. Yeah, that happens in v2_develop as well.

Do you think it's a bug on the Dim.Auto (DimAutoStyle.Content)?

We're missing SetLayoutNeeded or LayoutSubviews somewhere.

IIRC, I think I suspected it was someting to do with SubViewsNeedsLayout not getting set right. The logic of all of that is pretty complex.
