JavascriptComponentStorage::createOrUpdateComponentEntity should not create component entities during config sync

We've not been doing that since ~4 months earlier before you created this issue, since ✨ Create a ComponentSource plugin for JS components Active :

    if ($this->configInstaller->isSyncing()) {
      return;
    }
    $this->createOrUpdateComponentEntity($entity);

— \Drupal\experience_builder\EntityHandlers\JavascriptComponentStorage::doPostSave()

But AFAICT the problem is that the Recipes subsystem doesn't correctly signal that config is syncing, and I bet that is why you opened this issue!

That's why both you and I spent a lot of time figuring this out on ✨ Add automated image optimization to image component Active

    // @todo Fix upstream core bug in Recipes: it inconsistently claims to be
    // syncing when installing modules, but not when installing configuration.
    // Even though it is listed under `import`, and that should hence match the
    // behavior of the /admin/config/development/configuration/single/import UI.
    if (in_array('installRecipeConfig', array_column(debug_backtrace(), 'function'), TRUE)) {
      // Assert the bug is still present. This will start failing as soon as the
      // upstream bug is fixed.
      assert(!$this->configInstaller->isSyncing());
      return;
    }

… which you (@larowlan) +1'd as the solution for now 😊 So closing this issue.
