Summary REGRESSION(257538@main): CSS opacity doesn't work on dialog::backdrop

Since iOS 16.4 Beta 1, using the `opacity` CSS attribute together with a `background` on `dialog::backdrop` no longer works. Instead, there is always no transparency. See this demo: https://jsfiddle.net/marto55555/yktr52hw/ Expected behavior: When the dialog is open, the button in the background should be slightly visible.
