.modal-dialog computed z-index=0 in Chrome

I noticed that Chrome computes .modal-dialog z-index attribute as 0. Here is an example from modal demo in BS3 documentation:

And here is an isolated example: http://jsfiddle.net/L88E2/
The problem is that even if dialog itself looks and works completely fine, z-index=0 messes with plugins that calculate own z-index based on container.
P.S. I`m using Chrome 30.0.1599.101 m.

Such as bootstrap-datepicker, and yes, i know that you dont support 3rd party plugins, but dont you think that modals shouldnt have such unexpected behaviour?

That's because we were setting position: relative;. Adding that fixes the computed z-index.
