[2.0.12] Draggin belt over underground belt sideways does not work (MR)

[Mefisto1029]

Dragging the belt over 1 underground belt works fine, but with more belts strange things happen:
With 2 belts only first half of underground belt is created.
With 3 then the Middle underground belt is shifted to 4th lane? Notice that it changed direction to left.
With 4+ it's getting even more wild. Just watch video.

Another thing I found to add to this report.

Create an underground belt ghost that goes under something.
Attempt to drag-place the belt & tunnel.
The exit of the underground belt fails to place.
I've tried under a number of things, this seems to fail every time.
The expected behavior is the exit underground is placed.

Also, dragging over ghost belts places only the first half of the underground belt. This looks related:

+1 same, but interestingly, it also tries to do an underground with 5 (even though underground only allows gaps of four) see pic

Also happens if a splitter or belts are between the two undergrounds. (an empty gap works fine)

Interestingly, it seems to work fine if you drag the belt 'backwards' (Not in the direction of movement)
