When removing [1] a long-loading script element from a document, browsers seem to disagree on whether such removal should affect page rendering. A simple test — <a href="http://kangax.github.com/jstests/blocking_script_removal_test/">http://kangax.github.com/jstests/blocking_script_removal_test/</a> — shows that Opera (9.x - 11) and IE (5.5 - 9) immediately continue parsing the document upon element removal. However, in Firefox (3-4) and Chrome (9) the document parsing is blocked until script is loaded or times out (even when the actual element no longer exists in the document, has its "src" reference an empty string, and there exist no references to it).<div>
