Breadcrumbs scroll horribly with a touchpad :(

You try and scroll horizontally but it only reacts to the accidental vertical component of your scroll action.

wonder if this is the tooltip preventing scroll events.

Possibly related to #9394.

I can't actually test this because my laptop is sub par, however I believe this would be caused by the scroll event being additive.

@lampholder can you try this again on the latest develop?

For me, it still seems quite difficult to scroll horizontally. I guess there aren't any wheel properties that say "from touchpad"...? Ideally we wouldn't attempt to consider the vertical component at all from a touchpad.
