LibWeb: Revert blocking of task by source in EventLoop

Browse source 
This reverts commit 664611bae4.

It seems like the HTML spec has been misinterpreted and this text:
"... Note that in this setup, the processing model still enforces that
the user agent would never process events from any one task source out
of order."

does not mean we can't interrupt execution of task by a task with the
same task source. It just says they should be processed in the order
they were added.

Fixes hanging while navigating from PR list to PR page on GitHub.
