Labels autocomplete is missing some labels

When trying to set a label using quick actions some labels may be missing from the autocomplete.

Steps to reproduce

• Go to any issue on this project
• Type ~workflow::v on a comment text box

What happens

workflow::verification label does not show in the autocomplete list, however it is being loaded in the server side response.

Expected

workflow::verification label should show in the autocomplete list

This might be happening for other labels too.
