Describe the bug
After updating to Astroid Framework v3.3.12, accessibility errors regarding ARIA menus are reported by wave.webaim.org for the submenu items of the main menu. The ARIA labels for submenu titles display correctly, but WAVE reports "Broken ARIA menu" for submenu navigation (the menu uses tabs). This issue is now present on multiple sites using Astroid (example: kb.joomla.fr) and was not present in previous framework versions.

To Reproduce
Steps to reproduce the behavior:

1. Install Astroid 3.3.12
2. Open site or demo with submenu navigation
3. Run accessibility checker (wave.webaim.org)
4. Observe "Broken ARIA menu" errors for submenus

Expected behavior
Submenus should have the correct ARIA markup and pass accessibility validation tools such as wave.webaim.org. Previous Astroid versions had submenu ARIA properly configured.

Relevant code snippets related to submenu ARIA rendering:

From js/megamenu.js (AstroidMegaMenuPro class > injectARIA function):

// Submenu ARIA rendering
subTrigger.setAttribute('aria-haspopup', 'true');
subTrigger.setAttribute('aria-expanded', 'false');
if (!subMenu.id) {
    subMenu.id = 'megamenu-sub-' + Math.random().toString(36).substr(2, 9);
}
subTrigger.setAttribute('aria-controls', subMenu.id);
subTrigger.setAttribute('role', 'button');
subMenu.setAttribute('role', 'menu');

From framework/library/astroid/Component/Menu.php (Menu component class):

echo '<nav class="..." aria-label="'.$headerType.' menu">';
... (submenus are rendered as `<ul class="nav-submenu megamenu-submenu-level-1">`)
