Bug 15768 – REGRESSION: hit testing fails in nested <svg> elements

• Component: SVG
• Status: RESOLVED FIXED

[Andreas Neumann]

This is a regression - used to work in previous builds. The event sensitivity in nested <svg/> elements doesn't seem to work.

I think bug 15787 is a dup.

I'll reduce this into a DRT-compatible test, and then maybe we can run bisect-builds on it to find out where it regressed.

Marking this as a regression and bumping to P1 since it worked in shipping Safari 3.

DRT compatible test case

I've not actually seen this test succeed under a non-regressed DRT (I've not tried), so it's possible the test is broken, but I'm pretty sure it's right.

The bug is that:
        IntRect overflowBox = overflowRect(false);

returns {0, 0, 0, 0}

This happened when we split RenderSVGRoot out from RenderSVGViewportContainer.  The fix is probably just to implement computeAbsoluteRepaintRect (which will also fix other bugs!), but I haven't gotten around to that yet.  There is another bug about implementing computeAbsoluteRepaintRect in bugzilla.  I think the proper fix is to make overflowRect() work instead of building the rect some other way.
