Users can `undo` changes on forms that are collapsed

[travjenkins]

Bug
In the create/edit flows we collapse sections. If this happens we do not force the focus out of an input that is contained within the section.

This means while the field is hidden the user could hit ctrl+z and undo changes without knowing it

Expected
When a section is collapsed we should ensure inputs cannot have undo done on them

Screenshots

Testing on Linux Chrome - not sure about others

Additional context
This might be hard to prevent as when it is collapsed you can hit tab, type something, etc. and it does NOT interact with the field. So it seems this is mainly just undo and redo browser implementation?
