Short description of error
The fast and awesome new Line Project Tool doesn't work well when the object is transformed!

Not giving more redundant info because this is related to this bug (i.e., the Line Project Tool still has the same behavior as the already fixed behavior of the Trim Tools) >> https://developer.blender.org/rB6dda0779fcdef704a17ed3c0150073f77534d5e5
