How to reproduce:
1. Open the “BugReports“ project
2. In the Project window navigate and open the “Assets/SignletonBufferSystem.cs” script
3. Wait until IDE indexes all the files
4. Select the class name string “SingletonBufferSystem”
5. Right-click on it then from the context menu select “Go to declaration” or press F12
6. Observe lines 12 and 14

Expected result: The “GetSingletonBuffer” method arguments are not empty
Actual result: The “GetSingletonBuffer” method arguments are empty

Reproduced with: 1.2.0-exp.3 (6000.0.0b15), 1.2.0 (2022.3.25f1, 6000.0.0b15)
Not reproduced with: 1.0.16 (2022.3.25f1), 1.1.0-pre.3 (6000.0.0b15)

Reproduced on: Windows 11
Not reproduced on: No other environment tested

IDE reproduced on: JetBrains Rider
IDE could not test on: Visual Studio (Could not find a way to inspect the generated code)

Workaround: Use “SystemAPI.TryGetSingletonBuffer<SingletonBuffer>(out var buffer, true)” instead of “SystemAPI.GetSingletonBuffer<SingletonBuffer>(true)”
