It should be noted that the bugs logged below are in addition to Gerard Tabot’s bug list & other sources and the .

#	Name	Description
1	A media attribute that contains a recognised Media Descriptor isn’t truncated before it encounters a succeeding unknown or invalid Media Descriptor			Bug Ticket
2	Parsing of selectors that succeed an (invalid) end-tag open delimiter within the STYLE element (HTML4 spec violation)	Section 6.2 of the HTML 4 spec states >the first occurrence of the character sequence “ NOTE: Only paragraph #5 in the test case relates to this example	Test Case	Bug Ticket
3	Illegal parsing of a z-index decimal value, rather than an integer			Bug Ticket
4	Block-level elements in normal flow with rtl direction are not resized dynamically when window is resize; thus a page refresh is required for the layout to display correctly
5	‘Flash of Un-Styled Content’ (FOUC) when using @import rule	Initial analysis suggests that using the @import rule triggers FOUC, similar to the issues seen in IE6 & IE7.		Bug Ticket
6	Horizontal margin of block-level element (in normal flow, with an overflow value other than visible) creates horizontal space between aforementioned element and preceding floated element			Bug Ticket
7	Value of malformed width property is parsed
8	Horizontal clickable/:hover area of inline element (nested within a block-level element) is consistent with the horizontal clickable/:hover area of a block-level element in normal flow			Bug Ticket
9	filter property with vendor prefix doesn’t work, whilst property without prefix does work	This behaviour goes against the documentation released from IE regarding vendor extensions		Bug Ticket
10	A background-color value (other than inherit) specified within a :hover pseudo-class block isn’t distributed to multiple lines if the initial element selector contains background-color:inherit	Credit must go to Vasil Rangelov (a.k.a. boen_robot) for bringing this bug to my attention.		Bug Ticket
