Contents returned by document.body.innerText for raw JSON have changed

Description
The handling of raw content (application/json and application/hal+json) has changed, which breaks our existing integration for situations where endpoints return raw content instead on HTML.

Version
SDK: 1.0.1823.32
Runtime: Edge Canary, 116.0.0.0
Framework: Win32
OS: Win10, Win11

Repro Steps

1. Load JSON content into browser [https://jsonplaceholder.typicode.com/posts/1](https://jsonplaceholder.typicode.com/posts/1)
2. Open DevTool Console
3. Execute: document.body.innerText

WebView2 Runtime 114.* and earlier:
Raw JSON

Webview2/Edge Canary 116.*:
Some mangled version of the content.

Additional context
Note that response.body.textContent still return the original JSON, but also include trailing mangled content.

Also note that script injection workarounds fail since fetch is not allowed:

Possible workaround
Initial experimenting indicate this snippet as a possible workaround document.body.innerText.substr(document.body.innerText.indexOf('{')).
