Bug 226683 – Wheel event is not fired on any SVG element

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: SVG

[Jay Wang]

I am trying to bind a wheel event listener to a SVG group element with D3. It seems the wheel event is not triggered when I scroll on the group element in Safari (the group is not empty). It works fine on Firefox or Chrome.

For a demo, see this codepen (https://codepen.io/xiaohk/pen/oNZdwoO).

Interestingly, it works as expected if the wheel event listener is bound to the SVG element instead of one <g> element.

For example, see this codepen (https://codepen.io/xiaohk/pen/vYxjZdY)

This is actually applied to <rect> element as well which suggests the bug is applied to all SVG elements.

reduced test case

This test case shows the bug can happen with the SVG <rect> element.

I found that binding first a wheel event to a containing HTML element (like 'SVG' or document.body) makes this working.

This is because we don't build event regions inside SVG content.
