Re: [csswg-drafts] [css-text] 'tab-size' de facto applies to inline boxes (#5489)

The CSS Working Group just discussed `[css-text] 'tab-size' de facto applies to inline boxes`, and agreed to the following:

* `RESOLVED: Change the spec to say tab size applies to inlines but when that happens the number values apply to advance width from block container`

&lt;dael> Topic: [css-text] 'tab-size' de facto applies to inline boxes<br>
&lt;dael> github: https://github.com/w3c/csswg-drafts/issues/5489<br>
&lt;dael> florian: Currently applies to block but in impl applies to inline as well. Question is how? Stack or independant? From tests seems independent<br>
&lt;dael> florian: If you have a prserve-tab with a value of 7 you measure frmo edge and push to next independent of if other ones. All browsers seem to do this so would like to spec it<br>
&lt;astearns> ack fantasai<br>
&lt;Zakim> fantasai, you wanted to ask where to put this and to<br>
&lt;chris> sounds like we could standardize reality there<br>
&lt;chris> ok, fair enough<br>
&lt;dael> fantasai: Defined to apply to block so when font changes in paragraph tab stops line up. We knew at time impl didn't do that. I think it's not a question about line up with realitiy, there's a reason the spec is different. We can decide we can't do thing that is correct, but there's a reason why it was spec as different.<br>
&lt;dael> florian: I did not know that, thank you<br>
&lt;dael> oriol: I prop in issue that maybe could go in between current spec and current impl. Could say property applies to inlines and let authors change values in line boxes. If value spec is a number say it refers to advance size of space character of containing block.<br>
&lt;dael> oriol: In common cases keep good alignment but closer to current impl<br>
&lt;dael> fantasai: Works for me<br>
&lt;dael> astearns: And likely more web compat<br>
&lt;dael> florian: Works for me<br>
&lt;dael> astearns: Prop: Change the spec to say tab size applies to inlines but when that happens the number values apply to advance width from block container<br>
&lt;dael> astearns: That would change for all browsers?<br>
&lt;dael> oriol: Yeah, right now they use width of space of inline box.<br>
&lt;dael> florian: I will add a test for that<br>
&lt;dael> astearns: Objections?<br>
&lt;dael> RESOLVED: Change the spec to say tab size applies to inlines but when that happens the number values apply to advance width from block container<br>
&lt;dael> astearns: Thanks oriol for the solution<br>
