(Here is the code to generate the issue, and for convieniency I'm also attachin a zip that contains exactly these classes)

// buz/MyBuz.scala
package buz

class MyBuz

//foo/bar/Bar.scala
package foo.bar

class Bar {
  val a = new MyBuz // <-- quick fix import here suggest the wrong import, it should be `_root_foo.bar`
}

// foo/bar/buz/Buz.scala
package foo.bar.buz

class Buz

The import type quick fix currently suggest `foo.bar`, which is wrong. In fact, it should suggest `_root_foo.bar`.
