test: fixup worker + source map test
Browse files Browse the repository at this point in the history
The messaging code uses `Object.defineProperty()`, which accesses
`value` on `Object.prototype` by default, so some calls to the
getter here would actually be expected. Instead, make the list
of accessed properties more specific to the tested source map
code to avoid flakiness.
