There is an ID (overlay) in the overlay.tpl template of the core overlay module that serves as a wrapper for the contents. This is however conflicting with another ID (overlay) that identifies the overlay module in the module listings. This results in the latter inheriting the CSS properties of the former thereby causing undesirable results.
Proposed Solution:
Change the ID wrapping the overlay (line 25 of overlay.tpl) from "overlay" to "overlay-wrapper" and then edit the overlay-child.css (line 17) accordingly.
Thank you.
