Description

e.g.

julia> check_equal((;a=2, b=2), (;a=2,c=2))
Test Passed

This is because it hits the general iterator fallback.

This isn't super high priority, since it only comes up in chaecking add!! behavour
(as neither value is a AbstractTangent subtype).

Still would be nice to fix.
Need to channel it towards one of our overloads for structured types
