BBox: tolerate non-layouted child in layouted mode

Browse Source 
While mixing layouted and non-layouted views is not supported, we are
doing it in some cases, including translator preferences (which uses
layout, but the views may come from a translator add-on which doesn't).

So, try to handle that case and at least avoid crashes by calling
MinSize/MaxSize and other unsupported layout code on views which won't
handle it.

Fixes #12610.
