Description alex 2023-12-13 12:49:12 PST 
As of iOS 17.0, Safari disables IndexedDB in Lockdown Mode.

This makes sense when browsing arbitrary websites in Safari, opening links from Messages, etc. However, IndexedDB is a critical API for webapps that are explicitly installed to the Home Screen, as well as native apps using WKWebView with limitsNavigationsToAppBoundDomains = true.

I propose IndexedDB being available in these specific, domain-bound contexts during Lockdown Mode.
