Tooltip unnecessarily breaks into multiple lines when positioned to the right
Created by: hnrch02
A tooltip breaks into multiple lines when it is positioned to the right, even though there is enough space for it to move further to the left. This doesn't happen if it is positioned to the left.
See this example. (Uses #13718.)
