Acid3 Test Failures of KHTML

This is an overview of the remaing failures of KHTML on the Acid3 test. FF3.1 beta2pre scores 92/100, with 4 of the 6 colored boxes filled in correctly.

Test No Area Diagnosis Comment passes in FF3 passes in FF3.1
04 HTML Parser Parser bug: iframe missing text kid discard_until = ID_IFRAME+ID_CLOSE_TAG --- added in No Yes
13 DOM Range Unhandled mutation Yes Yes
26/27 JS + DOM Memory management Cycle breaking cleaning up too much Yes, but slow Yes, but slow
29 HTML Parser Parser bug: table missing whitespace kid Yes Yes
44 CSS Parser Misparse of html*.test selector (see below) Yes Yes
48 (red linktest failed) CSS  :visited doesn't match URL of part Bug in konqueror's history manager. Works in testkhtml Yes Yes
51 DOM2 Table Stray row Buggy test. Raised with Ian Hickson. Yes Yes
53 DOM2 Forms Not managing form's element collection when not in document. Yes Yes
70-80 Can't run due to 65/69 SVG, SMIL + XHTML No 72, 73, 74, and 80 pass; rest fail

Note: An upgrade to PCRE 7.7 is required to make tests 89 and 90 pass.

Random patch storage

These are not meant for commit, but more as a proof of analysis, and starting point for proper fix:

#16, red cat.

Ugly, but roughly correct.

html*.test { border: 2px solid red; margin: 5px; }
<body class="test">
  <p class="test">There should be no red borders here.

#48, red linktest failed

It's a bug inside KonqHistoryManager --- it ignores some inserts, which makes the link not :visited.
