ResourceManagerTags of type {project_id}/{tag_key_name}={tag_value_name} are not visible on UI after deployment

TL;DR

While creating autopilot clusters, I am also adding in Secure Tags using TF block which supports below three formats.

1. tagKeys/{tag_key_id}=tagValues/{tag_value_id}
2. {org_id}/{tag_key_name}={tag_value_name}
3. {project_id}/{tag_key_name}={tag_value_name}

When using #3 format of {project_id}/{tag_key_name}={tag_value_name} secure tags - The TF apply is successful and gcloud command gcloud container clusters describe <cluster_name> outputs the tag applied under ResourceManagerTag section. However on the Google UI - It does not reflect this change

Expected behavior

The applied secure tags to the GKE cluster need to be visible on Cluster UI under Tags (firewall)

Observed behavior

Applied secure tag of format {project_id}/{tag_key_name}={tag_value_name} is not showing up on Google UI on cluster details page
