Summary
Installed web apps can change the text on the title bar based on the page's content. The current behavior is that the installed web application will put the app's name from the manifest and append the page’s inner text from the `<title>` HTML tag in the head of the page. This often can create awkward titles for some web apps. This feature allows to specify complementary information about the current window of an installed running PWA. It adds a subtitle to the page to provide contextual information that is displayed in the window's title bar. This replaces the text contained in the HTML's title tag.

WebView application risks
Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
Goals for experimentation
Ongoing technical constraints
Debuggability
The DOM inspection in DevTools is sufficient.
Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
This is a feature that works on desktop scenarios (Windows, Linux, MacOS), mobile platforms don't make use of it.
Is this feature fully tested by web-platform-tests?
