When used with a remote source a "ajax loading spinner" is set on the background of the input box. When this occurs on a default input box with no styling, the border style of the input box changes when the gif is present via the background rule.

If you have full control of the app you're adding autocomplete  toyou can just set the border of the input box beforehand. However I'm trying to build an autocomplete widget that can be dynamically added anywhere and don' want to interfere with any current styles on the host page.

No biggie, just wanted to report it.

Thanks,
