Indeed context refontification is enabled by default, but that's only an
idle timer, so it shouldn't keep firing repeatedly while Emacs is idle.

No, the jit-lock-stealth code keeps on running for a potentially long
time after Emacs became idle (IIRC it uses a while-input-pending-p kind
of loop).  But yes, the timer only triggers once.
