[whatwg] Throbber response to XMLHTTPRequest() activity

[anko]

Hi,
It was suggested that someone email this list to see what you think 
about this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=312418.

Basically it's a request that the throbber (loading symbol up the top 
right of most modern browsers) should be active when XMLHTTPRequest is 
receiving data.  The idea is that the user stays informed when the 
browser is waiting on network activity.

Currently XMLHTTPRequest does not change the throbbers state and it is 
hard to know if an AJAX enabled website is doing anything.

Any suggestions/links to specs/feedback would be greatly appreciated.
