Weird repeating anomaly with test results

Hello.

Please see the screenshot:

The last element of the footer (and the page) – the email address – keeps disappearing and reappearing in the test results.

No actual changes have been made to this simple element in a long while.

Any ideas of what could be causing it?

Thanks.
