Created attachment 475073 [details] Safari merges content If you set via CSS a container inline-size to an element (static positioned) and inside that container element you have a break-out element (like a popover), in Safari the result looks like that popover merge in to the next container. Firefox and Webkit show it correctly in an expected way. Example Code: https://codepen.io/marcnetic/pen/QwWQBjX
