--- Comment #12 from Said Abou-Hallawa <sabouhallawa at apple.com> ---
All the attached tests have the following problems:

1. The wait-spinner element has the wrong url for the background image { background: no-repeat url("wait-black.gif"); }. This is wrong because the test gif was uploaded as an attachment to this bug and can't be accessed by naming it "wait-black.gif".

2. The spinner element is a <span> element whose text is a single <span> </span>. The css for #wait_spinner specifies a size of the spinner to be {32, 32}. The right way to do this is to use a <div> element instead.

3. The css for #wait_spinner specifies its "display: none;". And when the button or the link is clicked, the style of the #wait_spinner is changed from "none" to "block". The right way to do this is to set "visibility: hidden;" and change this to "visible" to show the animated image. "visibility: hidden;" accounts for the element in the layout.

I attached a test case which is working after fixing the background link, using <div> and the css property "visibility".
