Web UI: Move back and forth in video using horizontal scroll

When I play videos on my server using VLC I find it very convenient to be able to adjust volume using vertical scroll and to scrobble through the video (move back and forth) using the horizontal scroll. You can see this behavior in full-screen mode in VLC. Vertical scrolling for volume control works fine in the Plex Web UI, but horizontal scrolling also changes the volume, instead of moving through the video.

It would be great if the Plex Web UI allowed moving through the video being played by scrolling horizontally.
