Bug Report

Summary

• TSTL Version: 2.4.1
• Expected behavior: @internal tagged features are hidden in the d.ts files
• Actual behavior: Not hidden at all

@internal tag is not working at all. The features marked as @internal comment are being shown in the d.ts files, published onto the npm module.

Code occuring the bug

To hide the @internal tagged features in the d.ts files, stripInternal must be configured as true in the tsconfig.json file like below:

{
    "compilerOptions": {
        "stripInternal": true
    }
}
