[DropdownMenu]: DropdownMenuButton closes instead of opening the modal when "Show Modal" is activated via keyboard

[NatalliaAlieva]

Description

When a DropdownMenuButton is supposed to open a modal, it fails to work when triggered via keyboard. Instead of opening the modal, the action is caught by the modal's catch mechanism, preventing the expected behavior.

Steps to Reproduce

1. Open CodeSandbox example.
2. Use 'Tab'/'Shift+Tab' key to navigate to the Icon Button.
3. Press 'Enter' to open the dropdown.
4. Use the keyboard to navigate to the Show Modal option.
5. Press 'Enter' on "Show Modal".

Actual result

The modal does not open; instead, the action is caught by the modal's catch mechanism, and the dropdown closes.

Expected result

The modal should open when "Show Modal" is activated via the keyboard, just like when clicked with the mouse.
