zoom center is broken when page is scrolled in WebKit #15

Closed RandomEtc closed 14 years ago

If the map is still visible but the page is scrolled, the mouse wheel zoom center is offset.

This is the bug I thought was in Firefox, but Firefox turns out to be OK. I'm testing in Safari 5.0.1 (6533.17.8)

It should be broken in Firefox too. We are using clientX/clientY in map.mouse, and should be using pageX/pageY.

mbostock commented 14 years ago

Actually SVGLocatable.getScreenCTM should be operating in the same coordinate space as clientX and clientY, so this may in fact be a bug in Safari.

This bug has now been fixed in WebKit, and I've implemented a workaround for earlier versions:

Fixed in 2.0.3.
