element-ready

This might be a niche request, but "element ready" might be useful even without querying a selector: Is _this_ element/node that I _already_ have ready? The shape of this function depends on a few open issues in order for it to be self-contained: https://github.com/sindresorhus/element-ready/issues/68 https://github.com/sindresorhus/element-ready/issues/67 https://github.com/sindresorhus/element-ready/issues/64 Signature, either:

Snapshot ancestor siblings per matched element and track child mutations. Treat a next sibling as a parsing signal only if it existed at match time, unless the element is reparented or its children change; then allow later ancestor siblings. Apply the same stateful check to observeReadyElements. Fixes #64 This was the absolute simplest I was able to come up with the help of AI. Not sure it's worth the complexity...

Context: https://github.com/sindresorhus/element-ready/issues/62#issuecomment-3798835723 I think that the current logic () is the best we got, but I wish we could find a better heuristic, maybe something based on mutation sequence. For example: e.g. no mutations in but a new _any-parent_ sibling appeared _while waiting_ specifically avoided MutationObserver in favor of polling to improve performance and reduce complexity, so I'm not sure if this is worth it. However conflicts with extensions and other third party scripts (e.g. script appends advertisement frame to ) are still a real issue.
