The content area gates hit testing's descent into hoisted children, but it was built from their layout boxes alone. A hoisted child moved by a CSS transform paints and hit-tests at the transformed position (Node::hit_inner applies the transform), so a click on it landed outside the recorded area and fell through to whatever the element visually covers. Union the transformed corners instead. Signed-off-by: Dietmar Maurer <dietmar@proxmox.com>
