Top-level definitions in Scala are not found

[mrdziuban]

Describe the bug

Repository that reproduces the issue: https://github.com/mrdziuban/pants-scala-top-level-test

I setup a Pants build with two Scala files:

1. src/main/scala/example/Foo.scala with contents

   package example
   val foo = "foo"

2. src/main/scala/example/Bar.scala with contents

   package example
   val bar = foo

When I compile the project with pants check :: I get an error:

-- [E006] Not Found Error: main/scala/example/Bar.scala:2:10 -------------------
2 |val bar = foo
  |          ^^^
  |          Not found: foo

However if I modify Foo.scala to place val foo inside an object then everything works properly, so I believe the problem has to do with the top-level definition.

Pants version

2.30.0

OS

MacOS, I haven't tested on Linux.
