@mhofman discovered that
passStyleOf
was not validating that an error'sstack
property was a string-valued non-enumerable data property before concluding that it is a passable error. In fact, it was not even validating that the value of thestack
property is passable. This flaw thus enabled data that was judged passable to carry non-passable data.This PR repairs that deficiency.
