Page crash iOS Safari in Private mode: infinite loop SessionStorage read warning about applicationinsights-js HOT 5 CLOSED

I also have the issue for my web site.

For Safari in private browsing the browser hands out the window.localStorage objet but throws an exception when using the SetItem member.

The problem is in Util.ts. The _getStorageObject and _getSessionStorageObject functions return the storage object but when the write functions use the storage object it throws an exception causing the write functions to return false. This causes the caller loop.

The _getStorage*Object functions should use a pattern where they validate the storage object by performing a test write operation before handing out the object. This is a common pattern - e.g. see https://mathiasbynens.be/notes/localstorage-pattern.

Hope the AI team can review the PR which should fix this issue. I can't run the unit tests locally, the PS script opens an HTML page with empty unit tests. I can test the results via Browserstack.
