Description Karl Dubost 2023-01-31 15:58:58 PST

Currently ::backdrop is visible for any elements in the Web Inspector. (reported by Simon Fraser)


a special case could be added to hide it in most cases, as it is already done for ::marker.
`if (pseudoId == PseudoId::Backdrop && !element->isInTopLayer())` (suggestion from Antti Koivisto)
