Hmm. To get this effect without preload=buffer, you could set
preload=auto,
watch the buffered attribute to see when some data is actually
downloaded,
then set it to preload=metadata to stop autoloading. That's a minor
hack,
and would need to watch out for browsers that don't autoload on
preload=auto, but it's probably good enough for the above cases.
It'd only
work if runtime changes to preload are applied, which would also be
needed
for scripts to implement "preload=auto only when paused".
I intend to make that impossible by only allowing scripts to increase
the effective buffering strategy
FWIW, this is what we've implemented in Firefox; we only allow changes
to the preload attribute after a load has started to increase the level
of buffering.
