According to https://bugzilla.mozilla.org/show_bug.cgi?id=1057329, sideways-right is already parsed since Firefox 35, so we could add a partial implementation since then.

Otherwise, Firefox 44 seems correct in terms of functionality: https://bugzilla.mozilla.org/show_bug.cgi?id=1193488

Renamed from vertical-right via WebKit/WebKit@608ae58 in WebKit 602.1.10 before Safari 10 (602.1.50).

Suggested change
"version_added": "10.1"
"version_added": "10"

Let's add the vertical-right value, which was supported since the beginning, see WebKit/WebKit@87bbc48 in WebKit 534.24 before Safari 5.1 (534.48).

Given that Chrome 25 used WebKit 537.22, I would expect this alternative name to also show up in Safari 7 (537.71).

Landed via WebKit/WebKit@57ac98a in WebKit 537.21, so it should also be in Safari 7.

Can we add it while we're here?

PS: Shouldn't we extract a separate subfeature for sideways-right? Based on WebKit/WebKit@b7bdc56, it was removed from the spec, so setting standard_track: true and deprecated: true should be the right thing to do.
