If a user installs a webpage as a PWA in Vanadium, is it using the webview toolkit, or the full browser?
The FAQ states ;
WebView-based browsers use the hardened Vanadium rendering engine, but they can't offer as much privacy and control due to being limited to the capabilities supported by the WebView widget. For example, they can't provide a setting for toggling sensors access because the feature is fairly new and the WebView WebSettings API doesn't yet include support for it as it does for JavaScript, location, cookies, DOM storage and other older features. For sensors, the Sensors app permission added by GrapheneOS can be toggled off for the browser app as a whole instead. The WebView sandbox also currently runs every instance within the same sandbox and doesn't support site isolation.
If a user were using a facebook and instagram PWA instead of installing Apps (as it appears many users here do) ... I take the above to mean they would share a single " WebView.. instance within the same sandbox and doesn't support site isolation"
Or do PWA's not use WebView? it sounds as if it would be most effective (isolated) to use the regualr Vanadium browser with each site bookmarked ... rather than install either the PWA or App
