We have evidence that implementors would not endure a compat impact by avoiding this step because weve been shipping like this and havent witnessed issues. Since removing it could yeild a performance improvement in the spec and there doesn't appear to be a compat impact, the spec would be better without it. 42446 1 934 jonas 2010-11-11 19:06:29 +0000 Created attachment 934 testcase Are you saying that for something like <html> <body> <form method="POST"> <input onclick="this.value = method;"> </form> </body> </html> IE throws an exception and doesn't alter the value of the input? For which versions of IE is this true? I'd love to remove this from Firefox, not just for performance reasons, but also to reduce complexity. 42474 2 jrossi 2010-11-11 23:42:48 +0000 Turns out IE behaves differently than I described and we can't assert that there is not compat impact for this. We should keep this spec'd as is. 54110 3 mike 2011-08-04 05:36:10 +0000 mass-move component to LC1 934 2010-11-11 19:06:29 +0000 2010-11-11 19:06:29 +0000 testcase test.html text/html 106 jonas PGh0bWw+Cjxib2R5PgogIDxmb3JtIG1ldGhvZD0iUE9TVCI+CiAgICA8aW5wdXQgb25jbGljaz0i dGhpcy52YWx1ZSA9IG1ldGhvZDsiPgogIDwvZm9ybT4KPC9ib2R5Pgo8L2h0bWw+Cg==
