Aman, as Mudit mentioned in earlier comments, this is working as designed and more discussions on this can be found at https://github.com/kubernetes-csi/external-provisioner/issues/199
Considering this is a generic behaviour, we would like to close this as NOT A BUG.
Please feel free to reopen if you think there is still enhancement required on this.
No plans to fix this RFE in 4.9, moreover we need to conclude the discussion happening in the above comments.
Moving it out of 4.9
Humble, please check if we can provide a clear description of the solution to the UI team.
