Fixed-size Buffer elements in the Visual Studio and Rider attached Unity debuggers are incorrect, except for the first Buffer value

Reproduction steps:
1. Open the attached project "FixedBufferTest.zip"
2. Open Project Settings -> Player Settings -> Other Settings and allow 'unsafe' code
2. Notice that "12 34 56 78" is being logged repeatedly in the Console
3. In the Assets folder open "FixedBufferTest.cs" script
4. In the Visual Studio top menu select Debug->Attach Unity Debugger and select the Unity Instance
5. Go back to Unity Editor and in the pop-up click "Enable debugging for this section"
6. Go to the script again and in Debug window local variables select foo->Buffer
7. Notice the Buffer values

Expected result: The Buffer values in the debugger are the same as logged to the Console ("12 34 56 78")
Actual result: The Buffer values in the debugger are different than in the console (except the first Buffer), for example - "12, 12260, \[...]"
