It's up to the application to inhibit idleness. See
gtk_application_inhibit().
For technical reasons, WebKit cannot use GtkApplication. We do take an
idle inhibitor using the freedesktop ScreenSaver interface, but there
is no explicit way to inhibit suspend that way. So we only inhibit idle
(screen lock) during video playback, not suspend. That seemed good
enough to me, because suspend did not previously happen automatically.
Changing this would be hard. See [1].
It would be helpful if gnome-session, or mutter, or whatever component
is responsible for managing inhibitors, would please not suspend the
computer when an idle inhibitor is taken via the ScreenSaver interface,
since that interface does not provide any explicit way to avoid
suspend. Maybe it already works this way, but I'm not confident of
that. Do you know about this?
