Fixes: #29142

This PR addresses an issue where the draggable legend in Matplotlib becomes stuck to the cursor after a scroll event while hovering over the legend. To "unstick" the legend, users must left-click, which is unintuitive.

This fixes the bug. I have two questions though:

  1. Why does a scroll_event trigger on_pick? That seems unintuitive to me.
  2. Are there possibly other events that come into on_pick and need to be escaped as well.

I think we should decide on whether we want that to happen, and if not, stop it earlier in the chain.

Thanks for the PR - I made a slightly different fix in #29842 to solve the issue, so I'll close this.
