[haslinghuis]

• Remember #2477
• ID works on saving - not on opening (already tried to store and retrieve the ID)

Some reference:

• https://developer.chrome.com/docs/capabilities/web-apis/file-system-access#storing_file_handles_or_directory_handles_in_indexeddb
• https://developer.chrome.com/blog/persistent-permissions-for-the-file-system-access-api

Doubt we can store this in security context - but will try
