When I run your code it passes on my side. I also checked the code and it’s fine. Try to refresh your page, and test again. Check also that you don’t have any extensions such as Adblock or Dark mode activated. The zoom of the page should be at 100%. If still it doesn’t work, verify if your browser is updated or just test on another browser. If you are on phone, check if the browser is updated too, and you can test on other browser.
