Cache busting query string breaks URLs with an existing query string

[kennethlove]

Problem

To enable Dioxus' hot reload, a random float is added as a query string to URLs for assets. If the URL already contains a query string, e.g. https://example.com?foo=bar, appending ?0.123435212 creates an invalid URL. This can interfere with requesting remote resources.

Steps To Reproduce

Steps to reproduce the behavior:

• dx new web
• add document::Stylesheet { href: asset!("https://example.com?foo=bar") }
• examine the requests made by your app, notice that the stylesheet asset has an extra query string

Expected behavior

To enable cache busting, I would expect a URL to get a new query string key/value pair when the URL already contains a query string, e.g. https://example.com?foo=bar&cache-bust=0.323432432. If the URL does not contain a query string, I would expect the current behavior, e.g. https://example.com?cache-bust=0.352432432.

Environment:

• Dioxus version: 0.6.0
• Rust version: nightly
• OS info: Windows 11 and Linux Mint
• App platform: fullstack
