/**
* Test behavior of 'align-self:auto' (Bug 696253)
* ===============================================
*
* The value "align-self: auto" is special. It's the initial value for
* "align-self", and it's supposed to compute to the parent's "align-items" value.
*
* However, to allow its style-struct to be shared by default, we internally
* make it compute to a special "auto" enumerated value, and then we resolve that
* to the correct value by examining the parent's style struct whenever we actually
* need to use it.
*
* This test makes sure that optimization isn't detectable to content.
*
* One special case of this is inheritance -- e.g.:
*
* <html style="align-items: baseline">
* <body style="align-self: auto; align-items: center">
* <div style="align-self: inherit">
*
* In that example, the child div's "inherit" should get the _computed_ value
* of "align-self" on the body. That, in turn, is "auto", so it should compute to
* its parent's "align-items" value, which is "baseline". So we need to end up
* with a computed "align-self" value of "baseline" on the child.
*
* (NOTE: if we instead allowed the child div to directly inherit the value "auto"
* from its parent, then we'd get different & incorrect behavior. The div would
* resolve that inherited "auto" value to its own parent's "align-items" value,
* which is "center" -- not "baseline".)
*
* This mochitest tests that situation and a few other similar tricky situations.
