…building stacking context tree (servo#45210) This was a small logic bug introduced in servo#44911. When building the stacking context tree we don't need to calculate containing blocks for queries, as they are calculated during the stacking context tree construction itself. This seems to improve performance from ~32k runs/s to ~35k runs/s on the `flexbox-deeply-nested-column-flow.html` benchmark (after servo#45208 is applied). Testing: This should not change observable behavior, but does improve performance. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
