Yes, a script (particularly a rogue one) redeclaring a function we 
defined in JS and which we call via JS_CallfunctionName. My primary 
concern was security, but I guess in a case like this what can be 
done is to have the function defined as a 'const' in the first place.
Thanks, and also for the very quick fix on 227432,
