### Bug description

If an extension has resources in a directory which is a symlink to some other directory, then the resource files don't get copied when they are added as HTML dependencies to the document.

```
.
└── _extensions
    └── myext
        ├── myext-resources   <- symlink to a directory with resource files
        │   └── <resource files>
        ├── _extension.yml
        └── myext.lua
```
