Loirooriol has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-logical][quirks] Should logical properties allow the unitless length quirk? ==
According to https://quirks.spec.whatwg.org/#the-unitless-length-quirk, some properties which accept a `<length>` must also accept a `<quirky-length>` in quirks mode.

Various of these properties have corresponding logical properties, which behave more or less like an alias. Should the logical properties accept a `<quirky-length>` too?

I was assuming that it shouldn't be accepted. However, I noticed that Chromium allows it in [these logical properties](https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/css/parser/css_property_parser_helpers.h?l=43&gs=kythe%253A%252F%252Fchromium%253Flang%253Dc%25252B%25252B%253Fpath%253Dsrc%252Fthird_party%252Fblink%252Frenderer%252Fcore%252Fcss%252Fparser%252Fcss_property_parser_helpers.h%2523ELcMnFMw0FiSYjySI9soH2cMoXCO3OJ6%25252BhKfFjoqfh8%25253D&gsn=kAllow&ct=xref_usages):
 - `scroll-margin-block-end`, `scroll-margin-block-start`, `scroll-margin-inline-end`, `scroll-margin-inline-start`
 - `scroll-padding-block-end`, `scroll-padding-block-start`, `scroll-padding-inline-end`, `scroll-padding-inline-start`

It's not allowed in the [other logicals](https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/css/parser/css_property_parser_helpers.h?l=43&gs=kythe%253A%252F%252Fchromium%253Flang%253Dc%25252B%25252B%253Fpath%253Dsrc%252Fthird_party%252Fblink%252Frenderer%252Fcore%252Fcss%252Fparser%252Fcss_property_parser_helpers.h%2523nhabkiztQB4yWSkXYJIDlbGwlEQmdFMz6Ag05c20bo4%25253D&gsn=kForbid&ct=xref_usages).

I didn't test them all but it seems that Firefox doesn't allow unitless lengths either.
