Describe the bug

Hi guys,

The issue is with keyboard navigation accessibility.

Steps to reproduce:

• navigate to Dropdown item with TAB and open it with SPACE or ENTER
• go down to menu items with ArrowDown keyboard key
• press ESC button to close dropdown

Expected behaviour:

• Dropdown popup should be closed and focus returned to the toggler, see proper behaviour here https://getbootstrap.com/docs/5.3/components/dropdowns/
• Able to press SPACE or ENTER key and open dropdown again

Current behaviour:

• focus stays somewhere inside the popup and doesn't return to a parent toggler.
• unable to open it with keyboard keys SPACE or ENTER
