Research direction
Investigate the 'Go To Definition' feature for type keywords in decompiled code. Focus on the decompilation metadata generation and symbol resolution in Roslyn. The bug occurs when navigating to `int` within a decompiled method. Check for missing mappings in the decompilation pipeline. Related files may include DecompilationMetadata.cs and SymbolResolver.cs. Comments in issue #25301 may provide additional context.
