What happened?

Hi there,

I found the page above results in empty layout shifts:

I used Lighthouse 12.3.0 run from CLI, something like:

lighthouse https://www.cin7.com/ --only-categories performance --throttling-method provided --screenEmulation.disabled --preset desktop --output json

Looking at the raw JSON, some items have a score but nothing else:

I am attaching the outputted JSON file, as well as the raw trace (running again with -G flag)

I can reproduce this. This is most likely caused by the nodes being removed from the DOM before the end of the Lighthouse run. If so, there isn't much we can do however we could still display some sort of "Node removed from DOM" message instead of just blank space.
