Symlinked assets regression

**Problem**

Because of https://github.com/DioxusLabs/dioxus/issues/3410, I had to make a full copy of the project in an adjacent directory, where everything is symlinked to `../original-project/`, except for `Cargo.toml` and now with v0.6.1 — `tailwind.css` (actually all explicitly used assets). I'm pretty sure it's because Dioxus checks fully resolved absolute path, which is indeed outside of the checked crate, so it gives this:

```rs

```

**Steps To Reproduce**

Steps to reproduce the behavior:

- `dx new test`
- `mkdir test-copy`
- `fd -d 1 -E target '' test -X ln -sr '{}' test-copy`
- `cd test-copy`
- `dx serve`

**Expected behavior**

I used this project with v0.6.0 and didn't have such issues.

**Screenshots**

- App platform: desktop

**Questionnaire**

I'm interested in fixing this myself but don't know where to start.
I would like to fix and I _think_ have a solution.
I don't have time to fix this right now, but maybe later.
