Bug - [Menu] - Clicking a flyOut group breaks the app

[lordrip]

Describe the problem
When using a Menu component with a flyOut submenu, clicking on a group, crashes the app.

How do you reproduce the problem?

1. Navigate through the menu elements using the keyboard
2. With the keyboard focus in one element, click in a flyOut group
3. Notice how the application crashes with the following error message:

Uncaught TypeError: can't access property "children", flyoutMenu2.getElementsByTagName(...)[0] is undefined

Reproducer: https://stackblitz.com/edit/vitejs-vite-nu1psm6y

Expected behavior
Clicking on any element of the menu shouldn't break the app.

Is this issue blocking you?
Unfortunately, yes, as we have a suggestion feature in Kaoto that uses this menu.
