Map widget if part of an object that is initially collapsed does not show when expanded

[m3dwards]

Describe the bug If the map widget is part of an object that is initially collapsed, when you expand the section the map does not show. Weirdly for me if I open dev tool the map immediately shows. I don't understand what opening dev tools does.
