Is there a way to get Win+Ctrl and Win+Alt to be sent as Ctrl and Alt, respectively, in a web-based virtual console?

At least as recently as Linux Mint 20, a behavior existed where Win+Ctrl would be the be sent to a web-based virtual console as Ctrl and Win+Alt would be sent as Alt, which would prevent browser shortcuts from interfering with console shortcuts. I have tried the Mint virtual keyboard, two different browsers (Firefox and Brave), and two different ISPs (Vultr and Frantech), and Win+Ctrl+\ is only sent to the virtual console as \. Note that using another computer with Mint 21.3 the behavior is the same. Is there a way to make Win+Ctrl be sent to the console as Ctrl and Win+Alt be sent to the console as Alt?
