This signal is emitted when the mouse cursor moves over an element such as a link, image or a media element.
To determine what type of element the mouse cursor is over, a Hit Test is performed on the current mouse coordinates and the result is
passed in the hit_test_result argument. The modifiers argument is a bitmask of ModifierType
flags indicating the state of modifier keys. The signal is emitted again when the mouse is moved out of the current element with a
new hit_test_result.
