Saved Pattern Entities Include Drupal Root In Cached Asset Paths

I'm uploading a patch of the current state of the MR for convenient access. This may be applied in a composer.json file with the following snippet:

{
  [...]
  "extra": {
        "patches": {
            "drupal/patternkit": {
                "#3380008: Saved Pattern Entities Include Drupal Root In Cached Asset Paths": "https://www.drupal.org/files/issues/2023-09-08/patternkit-3380008--fix-cached-asset-paths--4.patch"
            }
        }
  }
}

Testing revealed that the testing instructions I originally posted don't successfully reproduce the issue. Below is a revised set of instructions that should reproduce the issue as expected:

1. Install Patternkit, Patternkit Example, and Layout Builder modules
2. Configure a Node type to display with Layout Builder and per-node layout customizations
3. Create and save a new test Node
4. Edit the layout for the new Node, and create a new [Patternkit] Example block with test content
5. Save the layout
6. Move the Patternkit Example module folder to a new location in the Drupal installation, such as modules/contrib/patternkit_example/
7. Run the following Drush command to remove cached asset values:drush sqlq "UPDATE pattern_revision AS revision SET revision.schema=NULL, revision.template=NULL, revision.hash=NULL WHERE revision.revision IN (SELECT revision FROM pattern_revision)"
8. Rebuild all caches
9. Attempt to view the test page
10. Observe failed rendering for affected blocks

At this point, the resolution for this issue may be tested:

1. Install the patch for this issue
2. Run update hooks
3. View the test page
4. Expect to see the failed blocks loading successfully

Thanks for the thorough explanation and updating the instructions Stephen !!

I tried to reproduce as well re-verify the issue. Result looks good to me now.

Steps :

• Install Patternkit, Patternkit Example, and Layout Builder modules
• Configure a Node type to display with Layout Builder and per-node layout customizations
• Create and save a new test Node
• Edit the layout for the new Node, and create a new [Patternkit] Example block with test content
• Save the layout
• Move the Patternkit Example module folder to a new location in the Drupal installation, such as modules/contrib/patternkit_example/
• Run the following Drush command to remove cached asset values.
• drush sqlq "UPDATE pattern_revision AS revision SET revision.schema=NULL, revision.template=NULL, revision.hash=NULL WHERE revision.revision IN (SELECT revision FROM pattern_revision)"
• Rebuild all caches
• Attempt to view the test page
• Observe failed rendering for affected blocks
