First item on context menus always "hovered"

Current Behavior

When you open the Node-RED context menu by right-clicking, the first menu item always displays the hover effect, even if the mouse pointer is not over it.

Strangely, the effect disappears when you open the browser console and returns when you close it.

This issue is also present in Node-RED v4.

Expected Behavior

The hover effect should be present only while the mouse pointer is over the menu item.

Steps To Reproduce

Right-click on the workspace or the tab bar.
