Re: [csswg-drafts] [css-align] Does `vertical-align` on table cell set `align-content` safely or not? (#12220)

The CSS Working Group just discussed ``[css-align] Does `vertical-align` on table cell set `align-content` safely or not?``, and agreed to the following:

* `RESOLVED: when resolving align-content:normal on a table cell, we use safe alignment`

<details><summary>The full IRC log of that discussion</summary>
&lt;TabAtkins> oriol: when align-content:normal on table-cell, spec says to use vertical-align<br>
&lt;TabAtkins> oriol: so v-a:bottom acts like a-c:end<br>
&lt;TabAtkins> oriol: in some corner cases it might be possible to have contents of a table cell overflow the cell<br>
&lt;TabAtkins> oriol: these corners cases aren't very interoperable, but I could trigger them in both blink and webkit<br>
&lt;TabAtkins> oriol: wondering if these alignments, then should be safe or not<br>
&lt;TabAtkins> oriol: spec doesn't say whether it's safe or not, so I suppose eit's the default safety<br>
&lt;TabAtkins> oriol: but browsers dont' agree with that or each other<br>
&lt;TabAtkins> oriol: Gecko I coudln't trigger overflow anyway<br>
&lt;TabAtkins> oriol: fantasai said probably safe is better, i'm fine with that<br>
&lt;TabAtkins> fantasai: in general a lot of css2 stuff did safe overflow<br>
&lt;TabAtkins> fantasai: it's a better default behavior in many cases<br>
&lt;TabAtkins> fantasai: so given it's a legacy behavior, i'd prefer safety for vertical-align<br>
&lt;TabAtkins> astearns: other comments?<br>
&lt;TabAtkins> oriol: proposed resolution: when resolving align-content:normal on a table cell, we use safe alignment<br>
&lt;TabAtkins> astearns: concerns?<br>
&lt;TabAtkins> RESOLVED: when resolving align-content:normal on a table cell, we use safe alignment<br>
