            Bug ID: 218156
           Summary: iOS 14 Webshare API Broken - Promise never
                    resolved/rejected
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: Other
            Status: NEW
          Severity: Major
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: lhz0516 at gmail.com

On iOS 14 devices (test with iOS 14.0 and 14.1 / Safari) it works fine only once. For the second time it throws a permission error:


Error: NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.


Here are all the steps to reproduce:

     1. Go to https://mdn.github.io/dom-examples/web-share/

     2. Click the "Share MDN!" button

     3. Choose one of the suggested options or just click X to close the sharing popover

     4. Click on the "Share MDN!" button again

     5. See the error

We see the error because the previous sharing promise never gets resolved or rejected.
iOS 13 doesn't have the issue. Only iOS 14 has it.
