iframes no longer working with v0.7

**Problem**

I have a dictionary feature in my app that loads wiktionary in an iframe. This feature worked perfectly in v0.6.

In v0.7, wiktionary is loaded in an external browser. I checked out an earlier version of my app using v0.6 and wiktionary still loads fine, so it's not an issue with wiktionary changing their iframe policy.

**Steps To Reproduce**

Steps to reproduce the behavior:

- create basic app
- add a wiktionary iframe
- wiktionary should load inside the iframe, but a browser window is open

**Expected behavior**

The website loads inside the iframe.

**Environment:**

- Dioxus version: v0.7.3
- Rust version: 1.93.1
- OS info: macOS
- App platform: desktop
