Yeah, that does look plausible, and in fact certain.  ;)  The changes for bug 656197 changed the oredr of AfterSetAttr and the AttributeChanged notification: before that change we did AttributeChanged _before_ calling AfterSetAttr, but now we call it _after_.

The stack above is running under AttributeChanged and asserting that the value it got from the input is in the (min, max) range.  Now when it does GetMaximum(), since it's running _after_ the max attr has been removed, it gets back the default max value, which is 100.  But the value it gets from GetValueAsDecimal() is 383, because range inputs default the value to (min+max)/2 and the max in this case is 765, while the min defaults to 0. HTMLInputElement::AfterSetAttr is what updates the value to fit in the new (0, 100) range when the "max" attr is removed.  But that used to happen after AttributeChanged, so we hit the assert.

In the new world, we finish updating all our internal state before telling people that it changed (the whole point of bug 656197), so everything is much better.  ;)
