[bug] Hovering over multiple options leave them selected/highlighted

[rdlf4]

Hello,
I managed to find a bug with the Material-black controls. When right-clicking on an application icon from the taskbar, it will display a menu with options. Hovering over those options will change the color for the time that menu is still being displayed, even when the cursor is no longer hovering over that option, it shouldn't be like that. It seems this bug only happens with taskbar icons, but on application menus, that bug isn't there. The following is a link to a MKV video file link recorded with SimpleScreenRecorder: https://drive.google.com/file/d/1lO9D0w2eDjYrmL0fE0fDY2vhe3UDIMSd/view?usp=sharing (GitHub doesn't accept mkv and after converting it to GIF using KDENLIVE, it output a huge file (~480MB), which is too big to attach to this post.

Please have a look at it.
Keep up the great work.

Regards.
