Is the reason this doesn't make sense because page scale factor is only set by
the user or from the page itself so it must be after the frame is loaded?

[aelias_OOO_until_Jul13, 2014/03/10 21:43:42]

Right.  Early-ish in the load (after contents width is obtained) the page scale
is clobbered by the minimum scale, and then possibly by the history item, so
there's no scenario where we would preserve the previous page scale.  This test
only passed before because it didn't enable the viewport tag or set an initial
scale override.
