[ARM Tags] incorrect status code 202 at /{scope}/providers/Microsoft.Resources/tags/default

PATCH /{scope}/providers/Microsoft.Resources/tags/default on CRP Disk fails with status code 202
(tried with api-version 2021-04-01 and 2021-01-01, same response)

Same call on virtual machine scope and network interface scope is both good.

swagger (it only allow 200)
