Hold the menu hover left border, on the active admin menu on the top of the background color.

The latest version of WordPress comes with the hover/active bar on the left side. This is a great implementation, and it will add the cherry on the top of the user experience.

In addition to that, there is a slight improvement that might be needed to make is fruitful the whole experience. The implement is the scenario of perspective.

Suppose, I am on the Settings Page, by default, it has a hover active background color. If I move the cursor to the active menu then a white bar will appear on the left. But this white left bar should be on all time as I am on this menu and it's active.

The left vertical active hover bar should be on hold on the submenu item too when we will be on the settings of the submenu. Like this: ​https://nimb.ws/BvMYcK

Currently, the bar is appearing only when we hover the item with the mouse cursor.

Top menu list items and their children change background color to indicate an active state. The left border appears upon a hover state. For accessibility, it's important to keep menus consistent and not duplicate or overlap the states.

Thanks for your suggestion of an enhancement @reachmazharul! After discussion, we've decided that the change would increase confusability between the active and hover states. The active link state is already distinguished by the use of bold text, so it has an existing visual distinction that is acceptable.

Just noting that the current border for hovered or focused menu items was added in [49961] / #28599.
