> I'm guessing that position:relative isn't valid for the TD element, so WebKit drops it on the floor? Since I need to check it's existence here to match FF/IE , any idea how I can tell that it's set?

I'm not sure how you can tell if it's set or not, but I can verify that it's dropped on the floor in CSSStyleSelector.cpp::asjustRenderStyle:

// After performing the display mutation, check table rows.  We do not honor position:relative on
// table rows or cells.  This has been established in CSS2.1 (and caused a crash in containingBlock()
// on some sites).
if ((style->display() == TABLE_HEADER_GROUP || style->display() == TABLE_ROW_GROUP ||
     style->display() == TABLE_FOOTER_GROUP || style->display() == TABLE_ROW || style->display() == TABLE_CELL) &&
     style->position() == RelativePosition)
    style->setPosition(StaticPosition);


Perhaps we need a method to track whether we corrected away from the specified positioning in this case?
