Investigate element removal #41

Closed npm1 closed 3 years ago

npm1 commented 5 years ago

The spec does not handle element removal at all. When content is removed, previous content could become the largest, and a new entry would need to be exposed for such content.

Update: we're investigating whether element removal should be in the spec; we found several cases where it has a very negative effect on carousels: https://github.com/anniesullie/LCP_Examples/blob/master/removed_from_dom/README.md

Currently working on gathering a larger data set.

Ok changed the title as the spec and explainers now roughly cover removal. If we choose to not handle removal then they need to be updated.

We've decided to allow removed content to remain as valid LCP candidates, so now we need to update the explainer and spec accordingly.
