*Steps to reproduce:*
# Create a new URP project
# Right-click Project > Create > ShaderGraph > URP > Lit Shader Graph
# Open this in Shader Editor.
# Ensure the tab is in a group, and then click off the tab so that another is focused instead of it.
# Create a new URP project. Observe your layout.

*Actual results:* The shader graph tabs you had previously opened carry over into the layout of the new project. When you click on the tab, it disappears.

*Expected results:* These tabs should not exist in the layout of a new project.

*Reproducible with versions:* 6000.0.23f1, 2022.3.49f1, 2022.3.1f1

*Not reproducible with versions:* 2022.3.0f1

*Can’t test with versions:*
* 2022.2.0a1 - project wouldn't open
* 2021.3 - not supported on Ubuntu 24.04

*Tested on (OS):* Ubuntu 24.04

*Notes:*
* If you don't do Step 4, this issue still occurs but is harder to catch as it opens when the project opens and then immediately disappears.
** The new project in step 5 doesn't necessarily have to be the same editor version, but the above might happen.
* Attached .mp4 of this occurring with a new project, but I think I've seen it happen when opening existing projects too.
