SUMMARY

Having set the "Window Management -> Window Behavior -> Window Actions -> Inner Window, Titlebar and Frame Actions -> Mouse wheel" option to "Change opacity", I am finding that, once I've changed a window's opacity to be something other than full opacity, I cannot scroll the wheel with the modifier key pressed to get it back to full opacity.

Further, the scroll wheel action still bleeds through to the underlying window, scrolling my browser window, for example.

STEPS TO REPRODUCE
1. Set "Window Management -> Window Behavior -> Window Actions -> Inner Window, Titlebar and Frame Actions -> Mouse wheel" to "Change opacity"
2. Use your modifier key while scrolling the wheel.
3. Try to scroll back to full opacity

OBSERVED RESULT

Opacity cannot return to full.

EXPECTED RESULT

Can get the opacity back to 100%
