Shuriken

-

How to reproduce:
1. Open user's attached "RibbonTrailsBug.zip" project
2. Go to Edit -> Project Settings
3. Select the Time menu item
4. Set the "Time Scale" property to 0.1
5. Select the "MoveThisAround" GameObject in the Hierarchy
6. Move it around in circles with the Move Tool in the Scene view

Expected result: Ribbon trails are connected in the correct order
Actual result: Ribbon trails are not connected in the correct order, some lines appear to cut across the corners of the trail

Reproducible with: 2018.4.24f1, 2019.4.4f1, 2020.1.0b16, 2020.2.0a18

Note:
- Setting the "Time Scale" property to 0.1 was to see the issue more clearly
