It has but not on paper. The F35 is a networked plan and can vector in better AC suited for dogfighting. It can dogfight, but rarely, if ever, will another plan catch it unaware. There is a reason it is given to our partners, not the F22. Imagine an AC that has countermeasures like a mini AWACS but has superior offensive standoff capabilities. Like some others have mentioned here, whatever 5th gen fighter is being introduced still won't catch up because the US has entered our two superior fighters as being ready now while working on a true 6th gen platform.
You don't send fast movers into areas where they will be shot down. You conduct SEAD (suppression of enemy air defense) and their SAM (surface-to-air missile systems). Electronic jamming, and counter measures first. Several ACS come to mind after that. B1B Lancer which occupies 1% of the enemies radar but you'll never hit it because it'll release and go supersonic to peel out the area and the almighty B-52 Stratofortress are both nuclear-capable and can be sustained in the air for intercontinental missions, meaning they never come out of the sky until they deliver their payloads. You won't shoot them down either because of how high it flies. The B-21 Raider will replace the B1B soon.
America’s F-35 Joint Strike Fighter is easily one of the most hotly debated weapons platforms in decades–and certainly one of the most controversial. The reasons why are quite obvious: with a total cost of $1 trillion over the program’s lifetime, the integration of game-changing technological...

There is no such thing as a on on one dogfight anymore. For that to happen, a whole lot of shit will have to have hit the fan. The US doesn't sortie like that or even two fastmovers without agile combat support by way of electric countermeasures. Or another strike package, However, if an F-22 or F-35 were somehow cut off, they would still be ok.
F35 can loiter outside of the operational battlespace and connect multiple weapon platforms and ACs as the thrust while maintaining track of everything within the network. On the ground and the air. It can also link with drones and satellites, Naval and SOF to vector enemies into the killbox. When it does this it becomes the hub and sits outside of visual range like a mini AWACS, it's still a fast mover and can respond on the fly if needed to enter the fray. Can a SU anything do that? No. Now ask yourself this question: Why hasn't Putin sortied the Su-57? Well here I'll help you out. If they send that unrefined POS up it will get blown out the sky by F22s and F35s.
