Label Sync Check Hangs on Dry Run if YML has entry with Alias and Name set to the same value.

Bug report

• I have checked other issues to make sure this is not a duplicate.

Describe the bug

Having a label with an alias equal to itself seems to hang the dry-run process.

To Reproduce

I have a simple yml based on the setup one from yarn. While editing for my use, I ended up creating this entry:

  "bug":
    color: &bug
    description: A bug
    alias: ["bug"]

I assume an alias being the same as the name is causing some unexpected behavior.

Expected behavior

Either an error if this isn't allowed, or the job finishing within normal time frames. A cancel button to stop the action once it starts misbehaving would also be nice.

Actual behaviour

20+ Minutes running, closing the PR or deleting the branch don't seem to cancel it.

[sysnet-ai]

Closing this out as it ended up being something different.
Thanks @maticzav for the offline help.

@sysnet-ai can you share more about the problem? I'm seeing the same long running dryrun job, but not sure if it's related to your issue here.
