*Steps to reproduce:*
# Create a new project.

*Either:*
# Open the Test Runner window under Window > General > Test Runner
# Restart the project.
# Check the context menu in Window > Panel

*Or:*
# If the Test Runner is already in the Layout of a new project, this issue can sometimes be seen right away without a restart.

*Actual results:* The Test Runner panel name should display as "Test Runner"

*Expected results:* The panel name is "Test framework for running Edit mode and Play mode tests in Unity. Part of the com.unity.test-framework package."

*Reproducible with versions:* 6000.0.2f1, 2023.1.20f1 {*}{{*}}(See notes)\{*}

*Not reproducible with versions:* 2021.3.38f1, 2022.3.28f1

*Tested on (OS):* Primarily macOS, also seen on Ubuntu 20.04

*Notes:*
* {*}{{*}}While I seem to be able to reliably repro in 6000.0.2f1,\{*} earlier versions are less reliable for me. This is the earliest version where I managed to repro in. Continuing to investigate, please contact if more info needed.
* Have only been able to reproduce this issue with Test Runner so far.
* There is no issue with the Panel name until after the project is restarted.
