Problem

Related to: #1522

In large files, you can get into a situation where there are 0 errors reported in the errors pane except for "Not showing N further errors and warnings". Obviously, this makes it impossible to actually fix the errors, since you don't know what they are.

Thus, the bug seems to be that the Lua language server is incorrectly ignoring errors suppressed by the end-user, since they are still counting towards the 250 hardcoded (?) VSCode limit

Reproduction steps

Use the following Lua file:

With the following .luarc.json file:

Then, you will see that there are Not showing 2551 further errors and warnings. in the "Problems" pane of VSCode.

Reproduce el informe con el archivo grande main.lua enlazado, el archivo .luarc.json proporcionado y el panel Problems de VS Code; después, compara el comportamiento con el issue relacionado #1522. Empieza por la ruta de diagnósticos/comprobación de sintaxis y determina por qué los diagnósticos suprimidos siguen contando para el límite visible. Se considera terminado cuando los diagnósticos genuinos siguen siendo accesibles en lugar de mostrar únicamente el mensaje "Not showing N further errors and warnings".
