Hello, is anyone else seeing a script run trying to sign into the site of the URL you ran a WPT on?
It’s happening on all three of my tests.
I’m running on Moto 4g chrome.
I’ve attached two screen shots one of the film strip view thumbnail and the other of the strip that shows the login overlap on top of the site.
Check the authentication tab in the advanced settings. It’s possible something is autofilling the password field (even though autofill is disabled for it). There is likely an ad on the page that is loading something from excelator and when their server sees basic auth headers it challenges for auth which pops the dialog.
