Steps to replicate the issue (include links if applicable):

• Open Firefox or Chromium or whatever on your desktop
• https://w.wiki/5xvW Explore this random Timeline query (yeah I know it's very nice: Open Source videogames by date)
• Use your mouse wheel to scroll the timeline

Kitten-proof steps to reproduce:

What happens?:

Nothing.

What should have happened instead?:

Vertical scrolling (when using the mouse wheel).

Horizontal scrolling (when using shift + mouse wheel).

Workaround:

The native scrollbar can still be used. The bug only affects mouse wheel.

Other information (browser name/version, screenshots, etc.):

It works in mobile (panning works). The bug is present only on desktop (scrolling).

I think there is some preventDefault() in some scroll listener. So I think it's a JavaScript bug, not CSS.

Quality control

Test pages:

• test in normal query screen (click play, try to scroll the timeline)
• test in embed screen (try to scroll the timeline)

• able to scroll on desktop with the mouse wheel in a timeline
• still able to pan on mobile using your finger (it was already working)
