* Implement slot-related algorithms Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Hook up slot elements to DOM creation logic Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Set a slot assignment mode for servo-internal shadow roots Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Assign slots when a slottable's slot attribute changes Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Properly compute slot name Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * ./mach test-tidy Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Update <slot> name when name attribute changes Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Implement fast path for Node::assign_slottables_for_a_tree assign_slottables_for_a_tree traverses all descendants of the node and is potentially very expensive. If the node is not a shadow root then assigning slottables to it won't have any effect, so we take a fast path out. Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Move slottable data into ElementRareData This shrinks all element descendants back to their original size. Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Address review comments Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> * Update WPT expectations Signed-off-by: Simon Wülker <simon.wuelker@arcor.de> --------- Signed-off-by: Simon Wülker <simon.wuelker@arcor.de>
