            Bug ID: 181849
           Summary: "Add to homescreen" apps don't share storage with
                    Safari
           Product: WebKit
           Version: Safari 11
          Hardware: iPhone / iPad
                OS: iOS 11
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org

Web apps run from the home screen don't share storage with Safari. Demo:

1) Visit https://www.scirra.com/labs/bugs/iosstorage/
2) Enter the number 123 and press "Save"
3) Add the page to home screen
4) Close Safari and open the home screen app
5) Press "Load"

Expected result: text should change to "Loaded: 123"
Observed result: text changed to "Loaded: null"

6) In the home screen app, enter the number 456 and press "Save"
7) Close the home screen app and open Safari again to the same page
8) In Safari, press "Load"

Expected result: text should change to "Loaded: 456"
Observed result: text changed to "Loaded: 123"

Our PWA (editor.construct.net) can save entire user projects in to IndexedDB. Users who use the web app risk losing their work due to this bug. It's also inconvenient since details like saved logins are not remembered between the two.
