Window.activate() not working in Jupyter Notebook

Works fine in a `cmd` but when I run it on a Jupyter Notebook (Colab local runtime):
```
import pyautogui
pyautogui.getWindowsWithTitle('Code')[0].activate()
```

VSCode flashes on the taskbar but never activated.

Strangely if I focus the window first with `pywinauto`:
```
import pywinauto
pywinauto.application.Application().connect(best_match='Code').top_window().set_focus()
```
then it would work normally, until I restarted the notebook. This only affects one window, other windows have to be focused with `pywinauto` before being able to be activated with `pygetwindow`.

Kernel output:
```
