Per the HTML5 parsing algorithm, <basefont> breaks out of "in head", so <base> gets appended to <body>, where it no longer establishes the base URL per http://www.whatwg.org/specs/web-apps/current-work/#document-base-url . This breaks relative references on the site. The appropriate fix would be making <basefont> in 'in head' insert an element for the token, immediately pop it, acknowledge the self-closing flag but not change the insertion mode. 36103 1 hsivonen 2010-06-11 06:52:18 +0000 It's reasonable to believe that bgsound needs the same treatment as basefont. The alternatives are: 1) Hoisting <base> back to <head> OR 2) Letting <base> take effect in <body> It seems that #2 isn't needed for Web compat if <base> stayed in <head> when written before </head>. Hoisting <base> to <head> seems pointlessly unstreamable compared to letting <basefont> and <bgsound> stay in <head>. 36104 2 hsivonen 2010-06-11 07:02:37 +0000 Both IE and Gecko's old parser treat <bgsound> as an element that doesn't close <head>. 36105 3 hsivonen 2010-06-11 07:11:58 +0000 ...and in "after head", basefont and bgsound should be hoisted to <head>. That is, they should be parsed just like <link>. 36106 4 hsivonen 2010-06-11 08:01:07 +0000 Furthermore, based on IE behavior, <basefont> and <bgsound> should not set frameset-ok to 'not ok' and it's not useful to make them reconstruct the list of active formatting elements, since they don't render anything visual. 36853 5 ian 2010-07-14 18:27:35 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
