The default display for anchor elements is "inline". jQuery will always make the best attempt to return elements to the display style that they were prior to being hidden. Please provide a complete reduced test case on jsFiddle to help us assess your ticket!

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: http://jsfiddle.net/FrKyN/

I found what was happening. if a [0x0] fadeOut() not working, while there is a picture of <a> with position:absolute

As mentioned, please provide us with a test case on jsFiddle.net that reproduces the issue experienced. Although you've noted what was happened, it still isn't clear as to whether this is the exact setup used to simulate the bug. If you can supply a test, we'll be able to assist further.

Because we get so many tickets, we often need to return them to the initial reporter for more information. If that person does not reply within 14 days, the ticket will automatically be closed, and that has happened in this case. If you still are interested in pursuing this issue, feel free to add a comment with the requested information and we will be happy to reopen the ticket if it is still valid. Thanks!
