I've just tested a new webpage on a dev site I'm working on in Page Speed Insights and one of the failing items is in the Accessibility section. It highlights an issue with the standard Joomla menu module.

Currently I only have 4 level 1 menu items, with a single level 2 menu item from one of the level 1 menu items. This single level 2 menu item is the one that generates the error.

If I test on the parent menu item of the failing level 2 menu item page, I get the same error in PSI.

It would appear that the aria-hidden ="true" attribute is being added by JS at some point as if I check the Source of the page with dev tool this attribute is missing from the HTML

But if checked with 'Inspect' the failing code is present.

It states:

[aria-hidden="true"] elements contain focusable descendents
Focusable descendents within an [aria-hidden="true"] element prevent those interactive elements from being available to users of assistive technologies like screen readers. Learn how aria-hidden affects focusable elements.
