Jatinder: Our options are to
either mirror IFrame visibility with that of the top level
document or giving the more granular IFrane visibility
including the applied styling and offscreen location.
... I have found there are two interesting cases where the
granular IFrame visibility may be useful: UA extension applying
a display:none style to cross-origin iframes or ad being
scrolled off screen and can throttle work. The first case does
seem like an edge case. The spec today makes a simplifying
assumption that anything in the visible page is visible.
... The goal is to reduce background interference. This goal is
relatively well met with the current spec, where pages in
background tabs are throttled.
Arvind: There are some cases that we haven't covered, like fully obscured window. Likewise, this can be another case that can be covered in the next cut of the spec.
Jatinder: If we do support this in the spec, I feel it should not be a normative requirement.
Arvind: I will respond to the
mailing list.
... The next topic was whether the visibility event should be
fired and state changed for the navigate away case.
Jatinder: I think we should make
an assumption that we should either fire the event and change
the state or not fire the event or change the state.
... Before the unload event, we are still visible, so we
shouldn't report as hidden then. After the unload event, the
page should be unloaded, so there shouldn't be any action that
can be taken by knowing the page is hidden. We should follow up
on the mailing list to understand why this behavior would be
desired.
Jatinder: As for TPAC, the proposed timeframe will be to meet between 1-5pm Tuesday afternoon. This gives us the morning to potentially chat with the WebApp Security WG. If we need more time, we can move the meeting to the morning.
