Still discovering things I don’t like about Liquid Glass. I just noticed that the tab-bar in iPadOS Safari has a slight padding, but there’s no obvious border between it and the page. If the site’s background’s a similar colour, it looks like it the margins are not styled correctly. Just awful.
Oh, it’s worse than that. I think it’s translucent and it adopts the background colour of the page, so every page looks like it has a miss-configured margin, unless you have a header with a different background.
