I'm looking for a workaround or polyfill for the z-index bug described in this report: http://code.google.com/p/android/issues/detail?id=31862
My markup and CSS looks basically the same as the one given in the bug report.
It'd be really great if somebody could give me a hint in the right direction on how to solve this.
I had the same problem, and fixed it by adding the following css to my popups:
-webkit-transform:translateZ(0);
