navbar menu items keep the `:focus` pseudo-class after exiting the pop-out submenu

On the demo website https://devcows.github.io/hugo-universal-theme/

• click on "portfolio". The dropdown menu pops out.
• click again on "portfolio". This hides the drop down menu
• move the mouse to the left, to "features"

The background color of "portfolio" remains as if it was still focused.

I think this is not desired. Is there a way to fix this issue ?

(tested with chrome 113.0.5672.126 and firefox 102.10.0esr on 64-bit debian linux)

forget it. It is still focused, silly me.
