Does the [Fire] trait interact with [Fire] Resistance?

[BastionofthePants]

When a weapon gains any type of elemental damage, like fire, the entire attack gains the Fire trait. So let's say a +1 Striking Greatsowrd has the Flaming Rune.

If a creature has "Immunities: Fire" or "Resiste Fire 10," would either of those abilities be affected by the Fire trait of the attack, or would they exclusively apply to the 1d6 of extra fire damage added by the Flaming Rune?

[HammerJack]

Resistance or immunity to fire would still only apply to the fire damage.
