IDE does not suggest importing accessors (from other packages)

Given:

package a

@DataSchema
interface Person {
    val name: String
}

open class TestA {
    val dfA: DataFrame<Person> get() = dataFrameOf("name")("a").cast<Person>()

    init {
        dfA.name // works, no import necessary
    }
}

class TestB : TestA() {
    init {
        dfA.name // works, no import necessary
    }
}

But when DataFrame<Person> is used from another package:

IntelliJ seems to be unaware that it can suggest to import a.name as it doesn't know this is available. Adding it manually does work:

Not sure if this is something we can fix on the compiler plugin side or the IDE somehow :)

Reproduce the example with DataFrame and inherited accessors across packages, then determine whether the missing import suggestion originates in the compiler plugin or IDE integration. Trace the relevant integration point and verify that IntelliJ suggests importing a.name for the cross-package case while preserving the working same-package behavior.
