Can't set sign text when using turtle.placeUp()

[Lignum]

When placing a sign with turtle.place or turtle.placeDown, it is possible to set its text by passing a string to the function. This does not work when using turtle.placeUp.

Just tested this and got odd behaviour, I placed the lowest sign first then went up and placed down and then forwards placing those two and then back to place up.
