Regression

No

OverlapCollider() registers an overlap only at specific points when a CompositeCollider2D with Outlines Geometry is used

Physics2D

-

How to reproduce:
1. Open the "Main" Scene in the attached "case_1174546-Composite_Collider_Bug" project
2. Enter Playmode
3. Open the Scene Window
4. Drag the Gray box to make its collider overlap completely with a green box collider

Expected results: Gray boxes that have their colliders overlap with green box colliders at any point become red
Actual results: Only gray boxes with colliders that overlap with the left edge of green box collider become red

Reproducible with: 2019.1.14f1, 2019.2.1f1, 2019.3.0a12

Additional notes:
1. Such an issue occurs only when Outline Geometry is set. Setting the Geometry to Polygons fixes the problem, but it is not a solution when a collision needs to be calculated outside the GameObject visual.
2. Project in versions before 2019.1.0a12 could not be compiled due to missing references to asmdef files.

    Resolution Note (fix version 2020.1):

    Internal overlap AABB was being calculated incorrectly. Also the edge-radius wasn't being taken into account.
