[ iOS Sim ] REGRESSION (r242986) Layout Test storage/indexeddb/modern/idbtransaction-objectstore-failures-private.html is a flaky failure

[Shawn Roberts]

The following layout test is failing on iOS Simulator Release WK2

storage/indexeddb/modern/idbtransaction-objectstore-failures-private.html

Probable cause:

Test has been a flaky failure since test was created in https://trac.webkit.org/changeset/195394/webkit

However since changes in https://trac.webkit.org/changeset/242986/webkit . The test is showing up on iOS Simulator for the first time and failing more consistently. Test behavior is different in testing in r242985, and is less flaky in that revision. 

Reproduced with: 

run-webkit-tests storage/indexeddb/modern/idbtransaction-objectstore-failures-private.html --iterations 500 -f --ios-simulator

Let's call this 

    bool didDispatchAbortOrCommit() const { return m_didDispatchAbortOrCommit; }
