[EuiContextMenu] Missing underline hover on link items in Firefox

[Dosant]

Describe the bug
EuiContextMenu item hover behavior is different in Firefox. For some reason the underline on hover is missing from links (a[href]) items, but present on buttons (div onclick). In chrome the underline is present for both links and buttons

Impact and severity
Very minor? Just have this the bug in Kibana open for a long time...

Environment and versions

• EUI version: 91.0.0 and before
• Kibana version (if applicable): main 8.13 and before
• Browser: Firefox
• Operating System: Mac

To Reproduce

You can see it in this demo in Firefox: https://eui.elastic.co/#/navigation/context-menu

When you hover "Handle an onClick" there is an underline;
When you hover "Go to a link" there is no underline

Expected behavior

Underline for both, like in Chrome and Safari

Minimum reproducible sandbox

This should be resolved now in latest EUI - I grabbed it as part of #7373.

Kibana will be fixed once elastic/kibana#173569 merges
