A collision shape that is a child of an Area2D node is not detecting the mouse properly - the area2d is supposed to perform an action whenever the mouse enters and exits the collision shape. There are two collision shape children of the aera2d node. When i hover the mouse above the first one, it works flawlessly. The second one, though, only activates when you hover over a specific area on the edge of the collision shape, instead of the whole collision shape as it is supposed to. I've encountered this problem before, but with a button control node, where the solution was to set the mouse filter to mouse filter ignore, however it doesn't appear to be a possibility here in an area2d and a collision shape.
