Someone beat me to it. From Rabbi Etan Tokayer:
[T]he Targum Yerushami cited by the Chizkuni explains that the malachim escorts were so excited by the presence of Yaakov Avinu that the went up to the Heavens to let all the other malachim know they had the chance to see a celebrity – Yaakov Avinu whose face was engraved on the Kisei Hakavod.”
(B1g B0y, that was this – “Another version reads (I think), malachim who said ?? ??????? ?????, they took credit for themselves, it was they who had to wait for this opportune time.”)
