Code

CSS: Count nested blocks when skipping.

Browse Source 
When skipping "@media print { #foo {bar: baz} pre {white-space: normal} }",
the previous code would look for the first "{" and then the first "}", and
fail to skip the "pre" rule.  Seen at support.microsoft.com.

I originally posted this change as part of attachment 383 to bug 722.
