Tests: Workaround IE issues in qunit-assert-domequal

Browse Source 
In IE, `option` elements may have different initial `option` colors.
They may initially all be transparent, but later the selected
option gets a blue background with white text; we now ignore it.

The logic of `qunit-assert-domequal` was also fixed to use the same
method of fetching styles in all browsers; IE used to get a legacy
one meant for IE <9 due to a mistake in the performed check.
