Description Matt Lewis 2017-06-22 10:15:07 PDT
Multiple tests from inspector are failing together on Sierra WK2 Release:
  inspector/indexeddb/clearObjectStore.html
  inspector/unit-tests/collection.html
  inspector/unit-tests/globals-uncaught-exception-in-test-suite.html

One of the tests was already a flaky timeout: inspector/indexeddb/clearObjectStore.html

All 3 test Have a similar Diff:

 -- Running test case: NoSuchObjectStore
+ERROR: TypeError: this._dispatcher is not an Object. (evaluating 'eventName in this._dispatcher')
 PASS: Should be an error attempting to clear an object store that does not exist.
 

All 3 test get the same error:
+ERROR: TypeError: this._dispatcher is not an Object. (evaluating 'eventName in this._dispatcher')

In addition, these test will intermittently fail with other inspector tests but fail together more often.

This is the second time a bug has been filed about this. See bug 171822.

From an inspector perspective this failure is absolutely baffling.

Duping to https://bugs.webkit.org/show_bug.cgi?id=171822 to consolidate.

Have we seen this since June? I'm really baffled by this one.
