The drawback is that the tooltip appears if there is an other window over, but according Laminar XPLMIsWindowInFront may return an incorrect value.

Thus, if you have a window at the front of the floating window layer (xplm_WindowLayerFloatingWindows), this will return true even if there is a modal window (in layer xplm_WindowLayerModal) above you. (Not to worry, though: in such a case, X-Plane will not pass clicks or keyboard input down to your layer until the window above stops “eating” the input.)
