I can reproduce on Windows, but not on macOS. In Chrome, the picker seems to be able to exceed the window bounds, so this does seem Electron-specific.

same issue on versions 13.x and 14.beta, Windows 10 64bit version 2004

The same issue occurs with the new EyeDropper API introduced in Chromium 95 (tested in Electron 16.0.0-beta.9).

The same issue occurs with the new EyeDropper API introduced in

Electron 16.0.0-beta.9

Node 16.9.1

Chromium 96.0.4664.35

Currently the following version all limit the Eyedrop magnifier circle rendering inside of the browser window: (Win10 21H2 19044 x64)

• electron-v16.0.5-win32-x64
• electron-v17.0.0-alpha.5-win32-x64
• electron-v18.0.0-nightly.20211223-win32-x64

Test by drag & drop the test script file onto each electron.exe:

// quick-test.js
(async () => {
  const { app, BrowserWindow } = require('electron')
  await app.whenReady()
  new BrowserWindow({  width: 800,  height: 600})
    .loadURL('https://developer.mozilla.org/en-US/docs/Web/API/EyeDropper#result') // use MDN sample to test
})()

Then use the MDN sample to test

On same system Chrome 96.0.4664.110 and nwjs-sdk-v0.59.0-win-x64 all open & pick outside window area as expected.

The problem seems to be related to the Eyedrop magnifier circle not keep rendering & following the mouse pointer to catch & consume the next click.
If the clicking outside is at the taskbar & cause the Electron window to minimize, the color picking is not stopped and the mouse pointer will not show inside the restored Electron window, clicking at the Electron window titlebar seems to end the color picking process and fix the pointer rendering.

Update: the following version still limit the Eyedrop magnifier circle rendering inside of the browser window: (Win10 21H2 19044.1586 x64)

• electron-v17.2.0-win32-x64
• electron-v18.0.0-beta.6-win32-x64
• electron-v19.0.0-nightly.20220324-win32-x64

Update: the following version still limit the Eyedrop magnifier circle, now with red-colored grid lines in Win11 dark mode (Win11 21H2 22000.708 x64)

• electron-v20.0.0-alpha.1-win32-x64
• electron-v19.0.1-win32-x64

+1 here.

On Windows 11 and Electron v 20.1.4 it does not allow me to pick colours outside of window boundaries
