Again, if there was any history of this being an issue, one of the hundreds (or perhaps thousands?) of interested parties would have pointed to it by now.
Does it really seem feasible that there wouldn't be a thermal (or otherwise) protection device? Without thermal overload protection, one of the possible outcomes would be thermal overload & all that goes with it.
Regards the motor being disabled completely, in both directions / not just one, that's also not necessarily true & would depend on how smart the motor logic / protection is & how it's been designed.
