When running under MSan this test is failing a CHECK in a flaky manner. The actual failure appears to be in the spell-check module and is potentially not directly related to the password manager.

Example run: https://uberchromegw.corp.google.com/i/chromium.memory/builders/Mac%20ASan%2064%20Tests%20%281%29/builds/38851


Error:

[94277:7431:0222/101507.307752:FATAL:spellcheck.mojom.cc(758)] Check failed: !connected. SpellCheckHost::RequestTextCheckCallback was destroyed without first either being run or its corresponding binding being closed. It is an error to drop response callbacks which still correspond to an open interface pipe.
