Mirage - No Exit Portal after Elder Guardian Encounter

Bug Report ID: #2,527,026,787

When following the elder guardian through the elder portal in a mirage zone, there is no exit portal to take you back to the mirage area after completing the boss encounter.

Even though there is no portal to bring you back like the version outside of the mirage, I realized I can still click F7 to teleport back to the mirage entrance rather than having to exit to character selection and reenter the original map.
