1684973 - Event offsetX/Y differ in Chrome and Firefox for mouse events in SVGs

Status: RESOLVED FIXED

(Core :: DOM: Events, defect)

Description

[Thomas Wisniewski [:twisniewski]]

Bloomberg's site is currently affected by the interop difference between Gecko and Blink, where mouse events' offsets in SVGs are relative to the event's target in Firefox, but the SVG itself in Chrome. There's a pretty lonely spec-bug for this here: https://github.com/w3c/csswg-drafts/issues/1508

My feeling is that while Firefox's behavior is more reasonable/useful, since this is causing webcompat issues, perhaps we ought to bite the bullet and match Chrome's behavior (which Webkit still seems to share)?

This matches other browsers. Needs a test, if the try server comes back
green.
