The document contains the following: <STYLE TYPE="text/css"> [...] --> <!-- --> <!-- -- > .xf { color: yellow; background: red none; } </STYLE> ...in the HEAD. The View Source displays the following: <STYLE TYPE="text/css"> [...] --><!-- --><!-- -->.xf { color: yellow; background: red none; } </STYLE> I believe this is a parser bug that is also causing bug #2781. (Note that viewsource gets a lot else wrong in that STYLE block, I am merely quoting the end part because that is what I noticed first.)

Lowering Priority to P3 and setting a M5 milestone

setting milestone to M4

Works now.. Leaving it for QA to close the bug.

Marking FIXED per engineer's 4/6 comments

Verified fixed.

At the test uri given, the following markup: <DIV> Some Markup Here </DIV> ...gets displayed like this: <DIV> Some Markup Here </DIV> ...in ViewSource. This collapsing of linear whitespace only appears to occur in lines. That is, vertical whitespace (line feeds, carriage returns) are not collapsed. Furthermore, the whitespace collapsing does not occur after start tags or in comments. It _does_ occur in CDATA sections (eg, STYLE element content).

Setting milestone to M6 and priority to P4.

Please clear FIXED resolution if this is still a bug.

Fixed by latest update to parsing engine.
