chrishtr has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-overflow-3] Standardize `overlay` as a synonym for `auto` == WebKit-ancestral browsers (including Blink) at one point implemented a non-standard `overlay` value for scrolling.This was never standardized (see [here](https://github.com/w3c/csswg-drafts/issues/7421) for a discussion of why it shouldn't be). Subsequently, WebKit made `overlay` a synonym for `auto.Gecko treats it as an invalid keyword. Blink still retains the original implementation (but the change to match Webkit is tracked in [this bug](https://bugs.chromium.org/p/chromium/issues/detail?id=1271942)). This also came up as a [compat problem in Interop 2023 discussions](https://github.com/web-platform-tests/interop/issues/187). I propose to put the current WebKit behavior (`overlay` is an alias to `auto`) into the spec as a web compat compromise, because making it invalid would likely break too many sites.
