REPL: Precompilation breaks on 1.11 if sysimage contains multiple exts with the same name #57939
Description
This will break if two different packages in the sysimage have the same named ext.
Not a problem on 1.12 because that was removed in #55210
And not a problem on 1.10 because REPL was in the sysimage back then.
