Student and instructor didn't realize the solenoid had stuck after
starting the engine. There was a bit of "funny noise" in the headsets,
but they didn't get alarmed until they saw the ammeter indicating a
massive charge rate. Engine noise will drown out most starter noise,
especially if the starter drive disengages with engine speedup as an
O-200 does.
One bush operator I know of installs a red indicator light on the
panel, wired across the starter feed, to alert the pilot to a stuck
starter. It isn't rare.
We always make sure the prop path is clear when turning on the
master. It's not wise, either, to hangar airplanes with wings
overlapping props.

Wow, you'd think if the starter stuck on, the first thing you'd
do is reach for the master! Quickly! Seen that happen on one
plane actually, when someone turned on the master, the prop
started spinning.

We had a starter solenoid weld itself closed and
burn out the starter.
