Support for html debugger is broken

Hi. Thanks for app ^_^

**Describe the bug**
I'm using insomnia with laravel html debugger(https://github.com/barryvdh/laravel-debugbar), which included in response. With new version, 2020.4, support for this debugger is broken. I can see HTML debugger part, but can't see visual part, which you can see on screenshot below(version 2020.3.3)

**To Reproduce**
Steps to reproduce the behavior:
1. Enable laravel HTML debugger
2. Request any data via GET/POST/etc
3. See HTML debugger part in response
4. Can't see visual part of debugger(on screenshot)

**Expected behavior**
I wish to see laravel debugger for GET/POST/PATH/etc requests if it is placed in response (HTML after json, for example)

**Screenshots**

**Desktop :**
- OS: [e.g. macOS 10.14.6]
- Installation Method: dmg
- App Version: Insomnia, broken 2020.4, work's with 2020.3.3

Start by reproducing the issue in Insomnia 2020.4 with a Laravel Debugbar response containing HTML after JSON, then compare it with version 2020.3.3. Confirm that the visual debugger panel is restored for GET, POST, and other requests, while retaining the HTML response content.
