Maciej,
If I have gotten this right: Aria-describedby=hiddenSection would be
presented as if it was a visible section. While
aria-describedby=displayNoneSection would get a text string
presentation. Thus, it seems like adding @hidden, could make
non-displayed sections more accessible or cause a more "semantic"
presentation.
But w.r.t. what you said about "continuations"/"a block is nested
inside an inline" [1], then does the fallback of <object data=image.gif
> count as a "shadow DOM" too? And did you work on fixing fallback of
<object> as well … ? After all, <object> defaults to display:inline and
it its content is hidden (but not irrelevant). (My question relates to
ISSUE-158 [2].)
It seems contrived if AT would treat
<object aria-describedby=x >
<div id=x hidden><p>Foo
</div></object>
different from how
<object aria-describedby=x >
<div id=x hidden><p>Foo
</div></object>
</object>
is treated. If fallback of <object> gets treated like the <canvas>
shadow DOM, then adding @hidden should not gain any thing. Which in
turn would diminish the risk that authors perceive it as if @hidden can
make invisible elements more "accessible". A question that pops up: Are
there elements - such as children of <object> - where @hidden does not
make sense?
