Description

when the developer sets:

await firestore.enablePersistence({
    synchronizeTabs: true
 })

all chrome tabs sync the local data via the indexedDB local data, so preventing updating the local store on "local updates" completely, means the other tabs will not receive those changes.

I need an automated test that confirms this.......... o_O

perhaps Cypress and a test site will be needed, but only if Cypress can do multiple tabs. (2 Cypress instances would not be the correct tab)

if not possible with Cypress I'm at a loss how to create an automated test for this.

Research direction
Investigate Cypress multi tab support or alternative testing frameworks like Playwright. Look at the repository's existing test setup in the `test` directory. Consider creating a test site that simulates multiple tabs using IndexedDB. Check if there are any related discussions or PRs in the issue comments for guidance.
