Browser extension testing

[guest271314]

To open the Isolated Web App window programmatically from a browser extension page

var tab = await chrome.tabs.create({url:'isolated-app://<ID>', active: false});
await chrome.windows.update(tab.windowId, {focused:false, width:1, height:1, top:0, left:0});

To set the Isolated Web App window to the first tab in the current window

await chrome.tabs.move(tab.id, {index:0, windowId: (await chrome.tabs.query({currentWindow: true}))[0].windowId});

Note, it is possible to open the Isolated Web App programmtically from a browser extension page, then move the Isolated window to the current window as a tab; and we can also include browser extension code in the signed Web Bundle that establishes a connection to an extension for message passing between the extension andthe Isolated Web App, and between an arbitrary Web page and the extension, for the ability to control the TCPSocket instance from any Web page and stream data to and from the TCPSocket writable and readable sides, respectively.
