This is an Electron Fiddle project to see if Electron works with Chrome's upcoming Multi-screen Window Placement API. It just opens a window to https://michaelwasserman.github.io/window-placement-demo/.

Note that until Chrome 97 is released and becomes a part of Electron, this API is only available with webPreference.experimentalFeatures = true when creating a BrowserWindow.

Tested through Electron 15 beta 4.

Current bug: Screens are recognized and drawn correctly on the demo page. However, there appears to be a bug where requestFullscreen() always opens on the primary screen.
