False positive with `-Wunused:imports` and renamed import in same package

[mrdziuban]

Compiler version

3.3.0-RC3

Minimized code

https://scastie.scala-lang.org/mrdziuban/e4rXAgetT5aGQLL1zt4BJw/9

package example {
  object test1 {
    val test = "test"
  }
  object test2 {
    import example.test1 as t1
    val test = t1.test
  }
}

Output

    import example.test1 as t1
                   ^^^^^^^^^^^
                   unused import

Expectation

The import should not be reported unused since the rest of the code in object test2 fails to compile without it. This seems to only happen when the renamed import comes from the same package as the code where it's imported.
