Greedy undo does not work for tiles

[Hares]

126636: Version 2.0.34 introduced new feature - greedy undo.

Steps to Reproduce

1. Select any tile-placing tool
2. Drag it (either manually or via planner)
3. Undo the last action

Expected:

• All dragging action is undone

Actual:

• Only the last iteration of dragging is undone
• This is inconsistent with greedy undo for dragging items (belts, powerpoles, etc)

P.S.
I still think greedy undo should be on separate hotkey (see discussion), but the inconsistency with tile placement is definitely a bug. Either both should be greedy or both should be non-greedy.

P.P.S.
I reported this bug in 2.0.34 release notes discussion, but it went unnoticed.

Edit
Version prefix in the topic name changed from 2.0.34 to 2.0.35 to match the version this is report is recorded on. (Even though first discovered and first reported on 2.0.34.)

More on topic. Dragging power poles is also undone one-by-one which is also inconsistent but perfectly fine for me.

Dragging poles is an explicit exception of this system. Tiles are simply not implemented.

Thanks for the report. I am considering this to be a feature request as undo merging was only implemented for entities.
