Describe the bug

This is a regression. I'm not yet sure since which Tiled version, but it affects 1.11.2 and master.

When resizing an object in a direction that affects its position, the undo commands are not merged, resulting in many undo steps to undo the resizing operation.

Steps to reproduce

Resize an object from a handle that also will change the position of the object.

Expected behavior

I expect to be able to undo the resize in one step.

OS version

Linux

Tiled version

1.11.2 and master.
