Sanic- Sentry integration: Sending 2 requests consecutively to an endpoint in a test function raised error

[namnguyenbk]

Environment

SaaS (https://sentry.io/)

Version

No response

Steps to Reproduce

• sanic==22.3.2
• sanic-routing==22.3.0
• sanic-testing==22.3.0
• sentry-sdk==1.5.12
• pytest==7.1.2

Hi guys. Recently I upgraded Sanic and Sentry SDK's version of my web app. Yet there is a problem.
Here I have a very rough Sanic web app and I also use Sentry for error tracking to demonstrate the problem:
I got IndexError: pop from empty list When trying to write a test where I fired a GET request to an endpoint and verify the HTTP response code then I did the same in the same test function.](https://github.com/namnguyenbk/sanic-sentry-bug/blob/main/test.py#L10). See full traceback below.

Expected Result

The test could run successfully with Sanic=20.12.1. Still, the latest version of Sanic and Sentry makes it fail. Not sure what's going on and whether it affects other parts of the application. 🙏 Anyone has ideas to work around or thoughts?

Actual Result
