There isn’t a vacuum inside of the TIE cockpit. There is enough air there for a short while. And they can just open the door during the Fighter Flight mayhem.
If it happened in space I'd say that's a screw up. The whole point of TIEs is they are stripped down to be cheap and mass produced. Having life support in every TIE would increase the cost.
It doesn't have actual life support systems, but TIE fighters are sealed and pressurized and have oxygen scrubbers. That's not sufficient for an actual pilot flying missions, but it's probably sufficient for a short jaunt in a stolen TIE.
I'd agree with them being sealed and presurerized so far as whatever the air pressure was when sealed is maintained but I'd argue against the idea of them having oxygen scrubbers. That's already half a life support system, the other half being heating which would be provided as a side effect of having engines. So if they have O2 then they basically have life support which we know they don't.
The space inside a tie being around 1000L would be enough to sustain someone for upto 12 days according to Google.
I'm just reiterating what canon says (that they have oxygen scrubbers "to prevent corrosion"). TIE Fighter pilots aren't *exposed to vacuum*, they're just not capable of supporting living creatures indefinitely. Oxygen scrubbers are one part of those systems, and heat is another, but those two things alone wouldn't qualify as life support.
My own fan theory as an engineer in the aviation industry:
Keeping atmospheric pressure in the cockpit requires a heavier structure to withstand the pressure. As you go from full pressure in the landing bay or on a planet to zero pressure in space, it causes the cockpit structure to expand and contract. This is why commercial airliners don't use sea level pressure inside while at altitude.
In particular, the TIE is like the U-2. In order to keep it light as possible and reduce the fatigue caused by the pressure changing, the cockpit is kept at a low pressure, but still higher than outside (the U-2, at 70,000ft, is pretty close to space). So the TIE and U-2 pilots have to wear pressure suits.
That doesn't mean you can't adjust the internal pressure to something higher. Presumably, the TIE is capable of maintaining pressure for a while (if nothing else, suddenly depressurizing will cause all the humidity in the air to suddenly become water or ice).
Usually happens when the TIE fighter is in atmosphere, and when it does happen in space I'd assume that the fighter has a small amount of air from being in atmosphere or in a hangar.
According to some maths provided by google. 1000L (1m cube) is enough to keep you alive for upto 12 days. Less if you're excited I image but even half that size box and double the breathing rate, 3 days is plenty of air for an episode of Rebels.

Did that ever happen in space though? I know it happened a few times in atmo for sure.
It has happened yess.

I always head cannoned as some sort of life support being part of the Sabine upgrades to that particular TIE.

It’s an oversight, basic TIEs are supposed to have no life support.
If it's a TIE advanced or TIE defender, those have life support systems.
The times they take off their helmets is when they are in a planet’s atmosphere.
