Not Clearing Issues

Nobody has claimed this yet.

### How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Windows

### What is the issue affecting?

Diagnostics/Syntax Checking

### Expected Behaviour

Running a Diag should only show current issues.

### Actual Behaviour

Without going into much detail I have a python program that converts files in one language into lua. When I run it the files obviously change and the "problems" tab count changes but when I click on some issues it will go away (if they don't exists anymore) even if I do a workspace diag run( clicking lua in bottom right and choosing "Perform workspace diagnosis") it still contains these like old diag issues, like they are not being cleared out.

### Reproduction steps

clicking lua in bottom right and choosing "Perform workspace diagnosis" issues are not cleared.

### Additional Notes

_No response_

### Log File

_No response_

Start by reproducing the stale diagnostics through the Visual Studio Code extension on Windows, using the bottom-right Lua menu's “Perform workspace diagnosis” entry point. Compare the workspace results before and after generated files change; done means removed issues no longer remain after a workspace diagnosis.
