Hotpatching: Editing tailwind class names does not generate css

**Problem**

When editing an existing tailwind string with hot patching enables, sometimes required css for it is not generated.
Client then requests the css file that does not exist.

E.g. from the web console:
```
GET http://127.0.0.1:8080/assets/tailwind-028ab187999b7510.css
[HTTP/1.1 404 Not Found 4ms]
```
This issue occurs with built in tailwind integration and standalone CLI

**Steps To Reproduce**

Steps to reproduce the behavior:

- clone `https://github.com/s3bba/dioxus-tailwind-hotpatch-repro.git`
- run the dx cli `dx serve --hot-patch`
- Open main.rs file and edit the tailwind class string to end with a different opacity (This will require tailwind cli to generate css)
- Save the file, "Hello there!" will loose the background color as new css file with the new class was not created

**Expected behavior**

When updating the class name, a new css file needs to be generated
