OK! This took a fair amount of poking before I finally narrowed it down. The cause of the problem I was seeing on Instapaper was actually code in the form:

(function(Thing) {
  Thing.whatever = "This breaks.";
  function Thing() {
    // referencing `Thing` in this inner scope here is what does it

It seems like referencing `Thing` inside the `Thing` function inside a function with `Thing` as an argument (wow) causes `Thing` in the outer function to reference the argument instead of the function declaration.

As far as what I was seeing with the inspector open, I have no idea whether it was related or completely different. Whether or not the cause is the same, the symptoms are.
