Is your feature request related to a problem? Please describe.

I frequently zoom the Image frame when attempting to scroll through Thumbnails, or scroll through the Thumbnails frame when attempting to zoom the Image. This is because the active frame, and mouse wheel action, is currently determined by the last frame to receive a mouse click.

Describe the solution you'd like

The mouse wheel action should change based on which frame (Image or Thumbnails) is currently moused-over. You should not have to click either frame for them to respond to mouse wheel.

Research direction

Start by reviewing the mouse-wheel handling for the Image and Thumbnails frames, using the linked issue discussion for context. Reproduce scrolling and zooming with the pointer over each frame. Done means wheel actions follow the frame under the mouse without requiring a prior click.
