[REQUIRED] Describe your environment

• Operating System version: macOS 11.6
• Browser version: 5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.0 Safari/605.1.15
• Firebase SDK version: 9.4.0
• Firebase Product: firestore

[REQUIRED] Describe the problem

Very similar in nature to #4076, if not the exact same issue.

Steps to reproduce:

1. Open app w/ firebase.firestore().enablePersistence({ synchronizeTabs: true }) (synchronizeTabs option doesn't seem to make a difference).
2. Manually change the address bar to a different path in your app.
3. App reloads but doesn't make it very far at all in the load process.

App does not make it past the "Opening database" step:

Relevant Code:

It looks like a workaround for this issue was merged in #5166 by changing the cleanup behavior for Safari 14. I changed this from navigator.appVersion.match('Version/14') to navigator.appVersion.match(/Version\/1[45]/) to have the patch work for Safari 14 and 15 and my app now loads correctly.
