Description

I enabled several OAuth2 providers for my gitea instance (namely GitHub, GitLab and BitBucket) and connected my gitea account to all three of these. When deleting any of the three linked accounts, the other two will also be deleted. The expected behaviour would be to only delete the one account, I want to remove.
Currently I cannot test this on try.gitea.io since there is only one OAuth2 provider enabled.
