Improve popup grayout with html/css

[vovahumnytskiy]

I know popup now has an embedded adjustment panel to change grayout’s blur/opacity.
However, I don’t like the result I get + it seems there is a conflict with CSS, because I applied custom CSS for a group inside the popup, and the popup’s grayout blur just disappeared.

Here is what Bubble’s blurred grayout + my custom CSS grey group inside look like. Sometimes as said above grayout just stops being blurred.

I have checked, and there seems to be no CSS conflict. Grayout blur just doesn’t work sometimes.
