Mistaking the css-variables for the flexbox-gap

[xiaoxiangmoe]

/* main.css */
.foo {
    --adapt-status-bar-fold-horizontal-gap: 1px;
    display: flex;
}

doiuse --browsers "chrome >= 49" main.css

main.css:2:1: gap property for Flexbox not supported by: Chrome (49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,83) (flexbox-gap)

But flex-gap is not used by this css now. Only css-variables are used.
