If I understand correctly min-width and max-width are automatically populated?
i.e. no need for duplication

@lahmatiy is there anything I can do to help this PR being merged?

It seems there is some mess in the dictionaries regarding size properties. Judging by the specifications and browser tests, all min-/max-/width and min-/max-/height properties, as well as their logical block/inline versions, support the same set of values. I replaced <-non-standard-width> with <-non-standard-size>, to which I added all vendor values, plus intrinsic/min-intrinsic (non-prefix aliases). Now, all properties are supplemented with <-non-standard-size> and stretch (which is in the spec and should appear in browsers):

<all-size-properties> =
    auto | <length> | <percentage> |
    min-content | max-content | fit-content | fit-content( <length-percentage> ) |
    stretch | <-non-standard-size>

<-non-standard-size> =
    intrinsic | min-intrinsic |
    -webkit-fill-available | -webkit-fit-content | -webkit-min-content | -webkit-max-content |
    -moz-available | -moz-fit-content | -moz-min-content | -moz-max-content

@Mouvedia Thank you for your effort and helpful links! Closing PR without merge, since I fixed the issue by myself.
