17196	[RFC] [Patch] Undo/Redo may change data in inactive layer	GerdP	GerdP	"==== What steps will reproduce the problem?
1. Create new data layer and add some objects
2. Create 2nd data layer and pan so that the data in the other layer is no longer visible
3. create way with two nodes
4. Press Ctrl+Z (Undo) tree or more times

==== What is the expected result?
Only the way in the current (newer) data layer should be undone
==== What happens instead?
Changes in the inactive layer are also undone. This is probably never wanted.
==== Please provide any additional information below. Attach a screenshot if possible.
I am not sure if this is intended since we have only one Undo/Redo tree instance. I'd prefer to have a separate Undo/Redo tree for each layer, else we should not allow to undo commands for a dataset that is not active.
