Thanks! The link shows an earlier spelling "In the Amarna texts it is
regularly
written รบ-ru-sa-lim (with or without the determinatives KUR URU and KI."
And a latter ~700BCE spelling ur-sa-li-im-mu.
The latter is argued to have a long i: being represented as -limmu instead of
-li:mu.
That may be so. Also, IF these are the most common signs for li and im, it
may well represent le:m, as they are also used for le and em.
They may be writing ur-sa-le-em-mu to represent Hebrew -shale:m.
