This is because hover can continue to send signals when hovering over other overlayed widgets (buttons, etc.).

Whether color area is currently hoverred.

This is not mutually exclusive with TrackWidget::bg_hovered. The color area is considered part of the BG.

bool _TrackWidget::icon_hovered

This is not mutually exclusive with TrackWidget::color_area_hovered. The icon is considered part of the color area.

CustomButtonWidget* _TrackWidget::top_buttons
