Different packages with the same module names override each other

[ohad]

Anything module related is a bit verbose, sorry!
I'm using this scratch repo: https://github.com/ohad/module-bug-report

Steps to Reproduce

ohad@ohad-coml-laptop:~$ cd dev/
ohad@ohad-coml-laptop:~/dev$ git clone https://github.com/ohad/module-bug-report.git

ohad@ohad-coml-laptop:~/dev$ cd module-bug-report/
ohad@ohad-coml-laptop:~/dev/module-bug-report$ cd a
ohad@ohad-coml-laptop:~/dev/module-bug-report/a$ idris2 --build a.ipkg 
1/2: Building Data.Structure (Data/Structure.idr)
2/2: Building ModuleA (ModuleA.idr)
ohad@ohad-coml-laptop:~/dev/module-bug-report/a$ cd ../b
ohad@ohad-coml-laptop:~/dev/module-bug-report/b$ idris2 --build b.ipkg 
1/2: Building Data.Structure (Data/Structure.idr)
2/2: Building ModuleB (ModuleB.idr)
ohad@ohad-coml-laptop:~/dev/module-bug-report/b$ cd ../c/
ohad@ohad-coml-laptop:~/dev/module-bug-report/c$ mkdir depends
ohad@ohad-coml-laptop:~/dev/module-bug-report/c$ mkdir depends/a-0
ohad@ohad-coml-laptop:~/dev/module-bug-report/c$ mkdir depends/b-0
ohad@ohad-coml-laptop:~/dev/module-bug-report/c$ cp -r ../a/build/ttc/* depends/a-0/
ohad@ohad-coml-laptop:~/dev/module-bug-report/c$ cp -r ../b/build/ttc/* depends/b-0/
ohad@ohad-coml-laptop:~/dev/module-bug-report/c$ idris2 --build c.ipkg 

Expected Behavior

Both client modules type-check

Observed Behavior

Neither client module typechecks:

1/2: Building IndirectClient (IndirectClient.idr)
Error: While processing right hand side of prf. When
unifying B = B and fromInteger 1 + ConstantA = ConstantB.
Undefined name Data.Structure.B. 

IndirectClient:7:7--7:11
 3 | import ModuleA
 4 | import ModuleB
 5 | 
 6 | prf : 1 + ConstantA === ConstantB
 7 | prf = Refl
           ^^^^

Because both packages have the same module Data.Structure, idris doesn't seem to find the module from package b.
