*Steps to reproduce:*
# Create a new URP project.
# Open Project Settings & Preferences windows, and check the Shader Graph page in both. Ensure Variant Limit setting in both is under 513, and do not close these windows.
# Window > Package Manager > Shader Graph > Samples. Install Production Ready Shaders.
# Open Assets > Samples > Shader Graph > 17.0.3 > Production Ready Shaders > Scenes > URPProductionReadyShaders
# Note the "Are These Spheres Pink?" text, and the pink spheres.
# Follow the steps on the text:

* Increase the Variant Limit to 513 in *both* Project Settings and Preferences.

*Actual results:* The spheres shouldn't be pink with the mentioned settings set to 513.  This persists after restarting the project and confirming that the variant limits are both at 513.

*Expected results:* The spheres are still pink.

*Reproducible with versions:* 6000.0.12f1 (17.0.3)

*Can't test with versions:*
* 6000.0.0b15 (17.0.3)
** Shader variant limit keeps resetting to 128 - no errors or warnings.
** Sample not available, even though the package version is the same as 12f1.
* 2023.3.0b10 (17.0.2), sample not available
* 2022.3.39f1 (14.0.11), couldn't get past UUM-75973
* 2021.3.41f1 (12.1.15), sample not available

*Tested on (OS):* MacOS Intel 12.7.4

*Notes:*
*
** Struggling to regression test as I keep running into UUM-75973 while trying to do this. Marking as not a regression for the time being. Please contact ticket reporter if further testing is needed.
** *If you set the Variant Limit to 513 before importing Production Ready Shaders, there is no problem, and it works as expected.*
** Using Metal.
