--- Comment #1 from Daniel Holbert <dholbert at mozilla.com> ---
tl;dr: Sorry for the trouble - looks like this is actually "Invalid".


Details: the spec text for display:inline-block;overflow:scroll is:
====
The baseline of an 'inline-block' is the baseline of its last line box in the normal flow, unless it has either no in-flow line boxes or if its 'overflow' property has a computed value other than 'visible', in which case the baseline is the bottom margin edge.
====
https://www.w3.org/TR/CSS22/visudet.html#normal-block

I guess that is pretty specific to inline-block, and I just found this in the flexbox spec (and grid has a similar chunk):
====
When calculating the baseline according to the above rules, if the box contributing a baseline has an overflow value that allows scrolling, the box must be treated as being in its initial scroll position for the purpose of determining its baseline.
====
https://drafts.csswg.org/css-flexbox-1/#flex-baselines

So, I guess this is "invalid" and the specs *require* this inconsistency between inline-block vs. inline-flex/grid here (weird).
