Hello- I have an issue with secondary webpages disappearing. Occasionally, when I am on a website, particularly when I am buying something or comparing items and a pop-out page appears showing what you selected, when I go to click on that 'secondary' webpage it disappears. It's not hidden between other open browsers or appearing on the taskbar. It's just gone. When I go back to the main webpage site and open up this pop-out page again, it will reappear. But the moment I click on this pop-out page it disappears. An example is attached with a DoorDash progress order. It seems that it only happens with "secondary" pop-out pages. It does not occur if the website creates a whole separate new non-pop-out page. I went into settings to try turning off and on pop-up to see if that does something but nothing. Thanks for your help in advance.
