Opera: Values other than "text/html" are treated as text Gecko: "text/html" and literal (case-sensitive) "replace" are treated as HTML, the rest as text. When we tried doing what Opera does we ran into compat issues back when. See https://bugzilla.mozilla.org/show_bug.cgi?id=313217 80769 2 ian 2012-12-31 05:18:00 +0000 Do you have to act as if the fourth argument is also set to "replace" in this situation? (i.e. is it just that the type argument is optional?) Or does it not replace in this situation? 80786 3 bzbarsky 2012-12-31 06:56:05 +0000 > Do you have to act as if the fourth argument is also set to "replace" in this > situation? No. Not replacing was not a problem in the cases we dealt with. We just treat "replace" as an alias for "text/html" in the third argument and the fourth argument behaves as normal (i.e. not replacing if it wasn't passed). 83981 4 contributor 2013-03-05 01:07:23 +0000 Checked in as WHATWG revision r7729.
