Improve error logging in Frontend Integration tests

I've run into a strange frontend_integration test failure!

You've come to the right place

What's the goal?

When there's a test failure in the frontend_integration test suite, we want to make sure:

• It is clear why the test failed.
• It is clear what lines of code are related to the failure.
• If possible, the failure message could point to how it can be resolved.

Let's identify cases where we're not meeting this goal and try to improve our error logging 👍

Okay, so what should I do?

If your frontend_integration test failure is not mentioned in the comments below, please add a new comment with:

• A description of the context
• A sample of the failure output
• A link to an MR or branch that has the reproducible failure

We'll use this to diagnose the problem and find out any opportunities to improve our error logging.
