Normally that's a result of a failed spark plug seal. If you have no other problems I would put new spark plugs in it and check them at the next oil change.
Vehicle:
Subaru Impreza
Since then I have take good care of it, replaced the brakes on schedule in August 2020 and then in August 2021 new spark plugs.
Pros: replaced brakes, new spark plugs
Vehicle:
Subaru Forester
My 2002 had a similar issue. In my case it was the spark plugs, $250 fix.

Pros: no problems

Mazda

I'm pretty sure that modern Mazda's do do this, only not in the situation you're describing. They use it for their stop start system to save having to fit a beefier starter motor and what not, simply inject an extra dose of fuel and fire the spark plug to get the engine going again.
Pros: saves beefier starter motor
Vehicle:
Mazda 6
Ours has been pretty reliable, had some issues with odd stalling once which was cured with new plugs/wires/carbon cleaning, rear shocks just went recently.
Pros: cured stalling issues
Cons: rear shocks went recently
Vehicle:
Mazda 5
