Using
Storage.clearDataForOriginwas taking up to 4 seconds and the specificStorageTypethat was problematic wasfile_systemswhich is the data involved with the File Systems API. Dropping this type improves the time down to under 100ms. We are theorizing that this is not a commonly used API and will not cause state leakage between tests. If, in the future we deem it necessary to clear this out, we will need to figure out how to make this more performant.Steps to test
How has the user experience changed?
