fix: invalid enum check in HoverFocusBehavior logic

[idootop]

Problem

The existing implementation uses the in operator to check if a string is a valid enum member in HoverFocusBehavior. This check is ineffective because the in operator checks for the presence of keys in an object, not string values.

Solution

This PR fixes the issue by replacing the in operator with Object.values() combined with includes() to properly check if the provided focusArgument is a valid string value of the HoverFocusBehavior enum.

The change ensures that the focus behavior logic is correctly applied, preventing any unintended focus behavior due to incorrect enum value checks.
