### Steps to reproduce

On an animation track using a bezier curve, select a key and try to change the handle mode from the inspector tab

### Minimal reproduction project

N/A
int key_idx = -1;
				float key_distance = 1e20;
				hovering_key_idx = -1;
				
				for (int i = animation->track_get_key_count(track) - 1; i >= 0; i--) {
					Rect2 rect = get_key_rect(i, scale);
					float offset = animation->track_get_key_time(track, i) - timeline->get_value();
					offset = offset * scale + limit;
					rect.position.x += offset;
					if (rect.has_point(pos)) {
						if (is_key_selectable_by_distance()) {
							const float distance = ABS(offset - pos.x);
							if (key_idx == -1 || distance < key_distance) {
								key_idx = i;
								key_distance = distance;
								hovering_key_idx = i;
							}
						} else {
							
							hovering_key_idx = i;
							break;
						}
					}
				}
				if (hovering_key_idx != previous_hovering_key_idx) {
					
					queue_redraw();
