I often try to use a feature and it doesn't work properly on one browser. It's nearly always mobile safari. This week, I've dealt with scroll-snap (which makes URL anchors work correctly with a sticky header) being supported but only for some layouts (every other browser works).

Today I spent hours debugging why pages with a particular iframe embed would log you out of the parent site on Safari / iOS. Possibly because the same first-party resource was requested from both outside and inside the frame? Not sure yet.

If you attempt to use localStorage from a private tab on safari, it reports that it's present and working, but raises an exception on any access (every other platform either does not expose localStorage in private tabs, or clears it after).
