Yes, it is there.
It checks for the display that the main app is on and uses that display size as the boundaries.
To be clear, are you talking about the verse popups when the cursor is placed over a reference? The should display to the right of the cursor unless the right border is too close and only then to the left. I am having trouble visualizing what is happening because if the cursor is near the left edge the popup should be to the right and not cross left into the other monitor.
