Description

When files or printouts are transferred out-of-band via HTTP, handling of frames is effectively deprioritized, with the majority of bandwidth being devoted to transfer of the file. In such a case, the browser spends most of its time handling the download, and leaves little to no bandwidth for user input, sync responses, etc., causing the connection to become unresponsive.

While it's important that files transfer efficiently, that transfer should automatically throttle itself enough that user input is still possible, and more so when graphical updates are occurring.
