At least for Floating Text and the text on the front of the journal item, making a new line will shift the text on that line over as if it were a visible character. Not sure if this has already been reported- seems like it’d be hard to find a pre-existing one for this without knowing how they reported it.
Type a line in Floating Text and press enter.
The newline character to not have an effect on the horizontal position of the text.
After pressing enter the row will shift.
I feel like this is self-explanatory enough to not warrant me opening OBS :[
It doesn’t seem to happen on the Santa’s Workshop sign, at least not that I could tell.
