Liquid Glass changed dimensions and viewport measurements for fixed position elements, amongst a whole host of positioning related bugs:

Many of the bugs were fixed in 26.1, but still, I had to fix it to use it.
I was surprised that not much of the entire web was broken, but a cursory search of commits showed that the WebKit/Apple team took the approach of coding in site specific hacks for popular sites (eg instagram, google search!) for iOS 26.
Maybe I’m not looking in the right places, but I rarely see fixed position elements in modern web layouts— I imagine that’s why you didn’t see more disruption.
They may not be used in layouts, but they can be present in cases like keyboard open (if you wanted to attach some controls above the software keyboard for example); or just ever growing compatibility hacks.
