Window id of the Electron browser window as a string (e.g. "1", "2"). This is the stringified
form of the Electron BrowserWindow.id (a number), set from the URL search params in the
renderer process. The main process uses the numeric BrowserWindow.id directly (e.g. via
platform.getFocusedWindowId). undefined until the renderer reads the URL parameter.
