[jQuery] BlockUI stops anchors from appearing in the url

[Kush Murod]

Hi,
I wanted to pass anchors to url so they would be bookmarkable just like 
tabs plugin. For some reason bookmark never gets passed to url.
Then after some time I've uncommented ajaxStart and ajaxStop like so

$().ajaxStart($.blockUI).ajaxStop($.unblockUI);

Only after this my bookmark values started passing into url.
My guess is blockUI prevents bookmarks to be passed on as soon as ajax 
starts

Can anyone explain the situation.

Cheers,
