some components are missing their sourcemap

[zcmerlin]

Describe the bug

I created a Vue 3 project using Vite and added multiple-level routes. After using the plugin, the automatic component import feature works, but in the development environment, some components are missing their sourcemaps. The configuration, project structure, and dependency versions are shown in the image.
