Allow web app windows to have a tab strip. This adds a new display mode "tabbed" and a new manifest field to allow customizations to the tab strip.
Currently PWAs in a standalone window can only have one page open at a time. Some apps expect users to have many pages open at once. Tabbed mode adds a tab strip to standalone web apps that allows multiple tabs to be open at once.
Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
chrome://web-app-internals can be used for debugging, and the new manifest field could also be added to the DevTools Application pane.
