Research direction
The issue is about a mixin using #[block] not expanding correctly. Investigate the mixin and block handling in the Pug compiler, likely in the lib/ directory. Focus on how the compiler processes mixins with block content and where the block expansion might be missing. Check the differences between regular mixin calls and those with block interpolation.
