            Bug ID: 244240
           Summary: Mouse wheel behavior on <input type="number"> is
                    changed by other elements with wheel event handler
           Product: WebKit
           Version: Safari 15
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Forms
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: azuma.ginkakuji at gmail.com

Steps to reproduce problem

1. Open https://jsfiddle.net/ytfh4r2k/
2. Focus the first input field and move mouse pointer on it.
3. Turn the mouse wheel on the first input field.
4. Then, focus the second input field and move mouse pointer on it.
5. Turn the mouse wheel on the second input field.

Actual: Each input field behaves differently: the value of the first input field changes but the value of the second input field doesn't change.
Expected: Both input fields behave in the same way.

I think it is strange that the wheel behavior changes by an event handler of not-self nor not-ancestor elements.

It behaves as expected in Firefox. Chrome behaves as the same as Safari. https://bugs.chromium.org/p/chromium/issues/detail?id=1355750
