Bug 275479 – Geolocation Permissions API on iOS does not report 24h grant as `GRANTED`

• Status: NEW
• Component: WebKit Misc.

After accepting a geolocation prompt twice within a short time frame on iOS, geolocation calls return location without additional prompts for the next 24h. During this time, the permission API reports `PROMPT`, not `GRANTED`

Using [this testing site](https://permission.site/permission-status), I tested the behavior of the permission API on iOS. I took these steps:

1. Enable Location Services in iOS settings
2. Enable Location Services for Safari in settings
3. Get a geolocation prompt -> Allow
4. Reload the page
5. Get a geolocation prompt -> Allow
6. Reload the page

Expected behavior

In step 6, `navigator.permissions.query({ name: 'geolocation' })`, i.e. "Permission Status" reports `GRANTED`

Observed behavior:

In step 6, `navigator.permissions.query({ name: 'geolocation' })`, i.e. "Permission Status" still reports `PROMPT`

We want to provide a consistent end-to-end experience between content-area UI and browser-side UX. To do that, we need to understand how the browser UX will behave if (for example) we call the browser’s geolocation API -- will a permission prompt be shown? Or is the permission already granted or denied?
