frivoal has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-overflow][css21] overflow:hidden SHOULD or MUST not be scrollable? == Via language that was carried over from css2, `overflow: hidden` is [specified in css-overflow as](https://drafts.csswg.org/css-overflow/#valdef-overflow-hidden) (emphasis mine): >This value indicates that the content is clipped and that no scrolling user interface **should** be provided by the UA to view the content outside the clipping region. However, the content may still be scrolled programatically, for example using the mechanisms defined in [CSSOM-VIEW]. I do not believe that this **should** is intentional, so we ought to replace it with **must**. `overflow: hidden` isn't meant to be scrollable except via script. Or is it? I'm asking because iOS has a bug where it is scrollable in some corner cases. But if we have **should** rather than **must**, then maybe it is not a bug.
