1349824 - SVG element z-order incorrect when using group elements

Status: RESOLVED DUPLICATE of bug 1141098

(Core :: SVG, defect)

Description

[Cedric Wehrum]

Steps to reproduce:

If you define elements in an inline svg in a certain order the elements should be rendered in exactly that order. This works in normal cases. It should work as well if these elements are inside a group element.


Actual results:

However if these elements are enclosed in a group element the z-index order seems to be messed up.
An example of this can be observed here: https://jsfiddle.net/hm9n9pgb/

(In case you don't observe the same behaviour this is a screenshot of Firefox with my setup: https://own.arrakiz.org/index.php/s/gn6XvLpUOSWLzyT )


Expected results:

The order of the elements should be the same no matter if they are enclosed in a group or not. View the above jsFiddle in Google Chrome and you will see that Chrome renders both cases identical.
