test/definitions/visual/help-panel.ts:23

• focusInputs() waits for a visible native input before dispatching focus events, but this AppLayout page renders no input elements. The setup will therefore time out before the screenshot is captured; remove this setup or target an element that the page actually renders.

      setup: async ({ page }) => {
        await page.focusInputs();
      },
