There is no possibillity calculate block's (div) new size after DOM modification (receiving MutationEvent like "DOMSubtreeModified"). It works in Gecko-browsers but no works in WebKit.
DOM Mutation Events were replaced by MutationObserver API, is this something we are looking to fix? Thanks!
It's unclear what this bug means. Maybe meant that we can't calculate the new offsetWidth / offsetHeight / getBoundingClientRect inside mutation events? Closing as Invalid since the description is unclear to what this bug entails.
