Support 'auto' for the 'quotes' property. CSS2 specified the initial value for 'quotes' as UA dependent, but WebKit and Blink returns an invalid value (empty string) which will not round-trip. Setting it to the empty string will remove the declaration instead of setting it to the initial value. css-content-3 instead uses an 'auto' keyword for the default UA behavior.
Fix brokenness in current implementation and align with spec and Firefox.
