Zachary D. Rowitsch de0afa12a1 Fix 4 rendering bugs: HTML table parsing, background-position axes, deferred absolute layout, half-leading line-height
- HTML parser: Add implicit tag closing for table elements (td, th, tr, tbody, thead, tfoot) per HTML5 §12.2.6.4
- CSS background-position: Swap axes when Y-only keyword (top/bottom) appears first or X-only keyword (left/right) appears second
- Canvas background: Propagate background image ID from root/body layout box to canvas
- Absolute positioning: Defer layout of absolute children until containing block height is finalized, fixing bottom:0 in auto-height containers
- Inline line-height: Implement CSS half-leading model (CSS2 §10.8.1) so line box height uses CSS line-height, not font metrics
- Anonymous text boxes: Inherit line_height and vertical_align from parent styles
- Default vertical_align changed from Top to Baseline per CSS spec

WPT: +3 promoted (abspos-containing-block-005, abspos-width-004, background-color-animation-with-table2), -9 demoted
