[Feature Request] Add options to onFcp onLcp to ignore specific elements #321

My company adds a very large, almost transparent image for watermarking on intranet page launch, which affects the calculation of the fcp lcp metric. I hope that some options can be added to circumvent the problem of actually invisible elements being involved in the calculation.

Closing this for now, since this is not an request for this library and more a question for what is eligible as LCP element.
