In this case the state should be the same.
eg 
g18 is active and shown before tool change.
G18 is active but G17 is shown after tool change
G17 is _never_ applied in this program (it's a lathe program)

Yes I have code to display things differently depending on active Gcodes
in Gscreen - for instance G95 to show IPR, but now after a tool change
that code is gone.
