Timeline scroll inertia causes unwanted thumbnails

I often accidentally activate enormous timeline thumbnails (I usually don’t want them visible) when I do the following:

  1. Use the Mac trackpad to quickly scroll the timeline horizontally some distance to the left
  2. Press Command to prepare a keyboard shortcut shortly after #1

Although I’m no longer actively scrolling on the trackpad when I press Command, the inertia from the initial scroll-fling is still running, and Aseprite interprets this as Command-scrolling to activate (huge) thumbnails. I believe this isn’t desired behavior for Command to retroactively affect the remainder of a now-released scroll gesture.

If this isn’t easy to fix, I’d prefer an option to disable Command-scrolling so I can stop doing this, please.
