It happens every now and then. Some library depends on another and a user opens an issue that belongs to the wrong repo. Can I move the issue to the other repo?
You
If you have the ZenHub integration you will see this button at the very lower-right when viewing an issue. This allows the issue to be copied to another repo in the same organization, or copied and closed.
And yes, "Move Issue" is a misnomer.
There seems to still be no way to move (copy and delete) or to just delete, a mistakenly-submitted issue.
EDIT: Beware, the v1 of this feature has major limitations like leaving behind some(most?) of the issue's metadata, not notifying subscribers, etc.
