protected function waitForOffCanvasArea() : void {
  // The data-resize-done attribute is added by the off_canvas_test module's
  // wrapper around Drupal.offCanvas.resetSize.
  $this->assertNotEmpty($this->assertSession()
    ->waitForElementVisible('css', '[data-resize-done="true"]'));
  // Remove the data-resize-done attribute so in scenarios where off-canvas
  // opens yet another off-canvas, waitForOffCanvasArea() is looking for the
  // attribute on a new dialog, not an existing one.
  $this->getSession()
