Lighthouse NO_LCP error due to offscreen animation

Since Lighthouse was updated to include the LCP metric my site doesn't get a performance score anymore. The error text asks me to rerun Lighthouse but I have done so multiple times and there's no effect.

#### Provide the steps to reproduce
1. Run LH on https://cddelta.github.io/portfolio/

#### What is the current behavior?
Performance score is not calculated as no LCP could be measured.

#### What is the expected behavior?
LCP can be properly calculated or Lighthouse fails gracefully with a performance score when it cannot be.

#### Environment Information
Tested on web.dev and CI server running latest Lighthouse.
