Linedef does not connect to the hypotenuse

(I noticed this error a very long time ago, and I think that someone knows about it, but I'll still make this report)

If you create a bisector of a triangle whose legs are longer than 256 units, then it simply don't connect to the hypotenuse.

This issue don't occur if the triangle is single and has no opposite sectors. Also, this issue don't occur if the hypotenuse is looking in the opposite direction.
