So talked offline with @frivoal and noticed that Gecko does _some_ ([code](https://searchfox.org/mozilla-central/rev/7531325c8660cfa61bf71725f83501028178cbb9/layout/generic/nsGfxScrollFrame.cpp#5411)) of the propagation to the viewport, kinda, only for scrollbar directionality. This was introduced by @dbaron in [bug 192767](https://bugzilla.mozilla.org/show_bug.cgi?id=192767). So I guess the constraints are: 1. We want to keep existing content working (at the very least orient the root scrollbars in the right direction when `<body>` is `rtl`). 2. We want interop. 3. We want to avoid orthogonal flows (though this may be less important than the previous two). Both current Gecko behavior and the resolution in #3066 achieve (1) and (3). So if any of those are implementable by other engines I'm fine with either (not terribly happy about #3066, but...). Gecko can also pretty easily I'd think just propagate the whole writing-mode to the viewport. That gives us (1) and (2) but not (3). -- GitHub Notification of comment by emilio Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4357#issuecomment-533440916 using your GitHub account
