Hi WebKit devs, I'm making <https://www.chromestatus.com/feature/5777880099323904> Blink's flexbox implementation support the keywords start, end, self-start, self-end, left, right. I.e. finishing flexbox's implementation of https://drafts.csswg.org/css-align-3/#positional-values. Neither Blink nor WebKit currently support those keywords in flexbox. wpt.fyi <https://wpt.fyi/results/css/css-flexbox?label=master&label=experimental&aligned&q=align-content-horiz%20or%20align-content-vert%20or%20align-content-wmvert%20or%20flexbox-justify-content%20or%20flexbox-align-self-vert-002%20or%20flexbox-align-self-vert-rtl-005%20or%20flexbox_justifycontent> This is a request for Webkit's position on implementing those keywords in flexbox. Thanks, David
