RigidBody sometimes misses reporting a contact

[ChronoDK]

Godot version:
3.2.1

Issue description:
The body_entered signal is sometimes not triggered on contact. Not entirely random, but depending on phsyics settings.

Steps to reproduce:
Download minimal project and watch the bounce counter in the console.

I've downloaded the project and the behaviour is the same. I'm using Windows 10 Home.

Setting the physics FPS to 120 seems to solve the problem.

120 FPS does seem to solve the problem. Including in my more advanced project. I guess performance will suffer though?

Reading the comments, it seems this is yet another case of #9071. See the comments at the end of that issue for possible workarounds.

#2092 also seems to be fixed at higher FPS. Could they be related?

I know this is an old issue but I have been experiencing this same thing randomly for a long time. Currently in Godot 3.6 beta 3.

The original reproduction project in this issue is no longer available, so I can't check if this is the exact same setup but is does sound like it.

I don't think this is about CCD or tunneling because the collision happens correctly, it's just not getting reported. For example, I have rigid body missile in my game that sometimes just bumps into its target (another rigid body) and does not explode because body_entered is not emitted.

@fractilegames Please upload a minimal reproduction project¹ to make this easier to troubleshoot.

Footnotes

1. A small Godot project which reproduces the issue, with no unnecessary files included. Be sure to not include the .godot folder in the archive (but keep project.godot).
   
   Drag and drop a ZIP archive to upload it. Do not select another field until the project is done uploading.
   
   Note for C# users: If your issue is not Mono-specific, please upload a minimal reproduction project written in GDScript or VisualScript. This will make it easier for contributors to reproduce the issue locally as not everyone has a Mono setup available. ↩

I can't reproduce this consistently. It happens randomly and not very often. I will see if can set up a project where this happens..

[fractilegames]

I created a minimal test project that brute-forces collisions between two rigid bodies:
MissingContactSignal.zip

That seems the trigger the issue usually in less than 10 tries, which is way more often than I see the issue in my game. It's actually suspiciously often. I hope I didn't make some obvious mistake in the project.
