Opening a file from search results ignores project-specific code style settings

1. Set a custom code style for a project, which is different from the global setting (e.g. globally use tabs for indentation, and in the project settings use spaces).
2. Find Usages in the project (C++ or Macro Usages)
3. Open a file from the search results
4. Edit it and save

It uses the global settings instead of the project specific ones.
