ICE when re-exporting proc macro from renamed crate (wasm32-unknown-unknown)

[tomusdrw]

The compiler panics when trying to re-export a proc-macro, and the crate that contains this macro is renamed in the Cargo.toml:

my = { package = "my-proc-macro", path = "./macro" }

Fails when targeting wasm32-unknown-unknown, haven't tested any other targets though.

The code here contains a minimal reproduction example:
