I guess css-overflow should also clarify this. Currently https://www.w3.org/TR/css-overflow-3/#overflow-control says
Applies to: block containers [CSS2], flex containers [CSS3-FLEXBOX], grid containers [CSS3-GRID-LAYOUT]
I guess "block containers" might include table wrapper boxes, but it's not much clear. Table grid boxes seem excluded.
The useful thing to do here is definitely to apply it to the table grid box, so I think we should stand by that resolution.

I think there may be valid arguments for both options, applying it to the wrapper could be useful to clip an overflowing caption:
<!DOCTYPE html>
<table style="border: solid magenta; width: 100px; overflow: hidden">
<caption style="border: solid cyan; width: 200%">caption</caption>
<td>cell</td>
</table>
On Blink it looks like:
If you want to clip the overflowing caption... just clip the caption?
The CSSWG resolved (https://lists.w3.org/Archives/Public/www-style/2012Aug/0298.html)
Only the 2nd part did actually go into the errata (as noticed in #2778), but presumably the 1st part still holds?
However, css-tables says the opposite! https://github.com/w3c/csswg-drafts/blob/c269215694fbefc1d26bfc5a94f40aeef4fe8ae7/css-tables-3/Overview.bs#L921-L924
This was added in 03639670c4e22b49dcf566471b01235eba742e65, and I don't see any reference to some CSSWG resolution overriding the one from 2012.
Browsers do not agree: Firefox applies
overflow
to the table grid, while Blink and WebKit apply it to the table wrapper.Due to the way the we implement table wrappers in Servo, it was easier for us to align with Firefox.
There are tests that assert it applies to the table grid: https://wpt.fyi/results/css/CSS2/css21-errata?q=s-11-1-1b
Agenda+ to either ratify the previous resolution, or ratify what css-tables says.
