• Status: RESOLVED INVALID

Qt clone of #65939 and #53512. Andreas, I remember you hacked on bounding box calculation a few days ago, do you have an idea how to solve this bug on Qt?

Yes, sir! I know just what to do about this..

http://trac.webkit.org/changeset/94236 rolled out the original CG patch so maybe we should wait a bit with this.

By the way, this landed again in http://trac.webkit.org/changeset/99460

This problem maybe causes bug 71766.

Minimal test case

Load the attached test case.  In the console execute:
document.getElementById('obj').getBBox()

Expected result:
SVGRect {height: 25, width: 50, y: 100, x: 100}
Actual result:
SVGRect {height: 31, width: 50, y: 97, x: 100}

The red rectangle represents the reported size of the blue shape.  (The red rectangle is static, it won't update when this bug is fixed.)
