Reproduction steps:
1. Open the attached project "LineRendererBug.zip";
2. Open the Hmm.unity scene;
3. Try to change the position of LineRendererBug object (value of Z vertex);

Expected results: the object is drawn only partly;
Actual results: the object will be drawn completely.

Note: This issue appears only when Alignment is set to Local (with view everything works fine) and when Use World Space is not checked.

Reproduced on: 5.6.0b10, 5.5.2f1, 5.5.0f3, 5.5.0a1.
