Manage Blob URL Partitioning During Fetching and Navigation

The 'PartitionedBlobUrlUsage' (Manage Blob URL Partitioning During Fetching and Navigation) policy controls whether Blob URLs are partitioned during fetching and navigation. If this policy is set to Enabled or not set, Blob URLs are partitioned. If this policy is set to Disabled, Blob URLs can't be partitioned. This represents the Blob URL behavior before Microsoft Edge version 135. The policy is scheduled to be available through Microsoft Edge version 146. After this version, the policy will be removed, and Microsoft Edge will no longer support unpartitioned blob storage.
