The fallback rectangle path is using incorrect coordinates. The path starts at (0, 0) and extends to (width, height), but it should start at (xMin, yMin) and extend to (xMax, yMax) to correctly represent the shape's bounds.

For example, if a shape has xMin = -50, yMin = -50, xMax = 50, yMax = 50, the current code would create a rectangle from (0, 0) to (100, 100), but it should create a rectangle from (-50, -50) to (50, 50).

Suggested fix:

hit_context.moveTo(graphics.xMin, graphics.yMin);
hit_context.lineTo(graphics.xMax, graphics.yMin);
hit_context.lineTo(graphics.xMax, graphics.yMax);
hit_context.lineTo(graphics.xMin, graphics.yMax);
hit_context.lineTo(graphics.xMin, graphics.yMin);

Suggested change

	hit_context.moveTo(0, 0);
	hit_context.lineTo(width, 0);
	hit_context.lineTo(width, height);
	hit_context.lineTo(0, height);
	hit_context.lineTo(0, 0);
	hit_context.moveTo(graphics.xMin, graphics.yMin);
	hit_context.lineTo(graphics.xMax, graphics.yMin);
	hit_context.lineTo(graphics.xMax, graphics.yMax);
	hit_context.lineTo(graphics.xMin, graphics.yMax);
	hit_context.lineTo(graphics.xMin, graphics.yMin);
