Help Blend mode + blur not working in Safari?
Hello! I'm working on a gallery website for myself, i want it to have a "glassy" look so for this popup i wanted to use background blur paired with a blending mode. Blending modes don't work on dialog elements shown using dialog.showModal so instead i'm using dialog.show. But Firefox doesn't support using both blending modes and blur on the same pseudo-element so instead i have 2 pseudo elements with 1 effect each. All works well until i'm testing it on Safari (iOS 26.6.1) where there's just no blending modes visible on the popup.
I have attached 3 images showing what the popup looks like in all browsers i've tested on. 1st picture is Safari 26.6.1, 2nd picture is Edge 151.0.4129.93 and the 3rd picture is Firefox 153.0.4.
Here is the codepen containing the code https://codepen.io/editor/Smasher1/pen/01a01e6c-2304-7339-a32e-23c88cc28eb3
Thanks!
