Testing custom Lint rule with custom scopes

Question

On the project I have a bunch of custom Lint rules. At some point of time I had a need to report single issue with different severity, depending on the scope. Since issue is tightly coupled with a scope I created two issues:

val ISSUE_1 = Issue.create(
   ...
   severity = WARNING,
   implementation = Implementation(MyDetector::class.java, Scope.ALL_RESOURCES_SCOPE)
)

val ISSUE_2 = Issue.create(
   ...
   severity = INFORMATIONAL,
   implementation = Implementation(MyDetector::class.java, Scope.RESOURCE_FILE_SCOPE),
)

Then in some place within the detector I've implemented the following logic:

if (context.scope.contains(Scope.ALL_RESOURCE_FILES) {
   context.report(ISSUE_1, ...)
} else {
   context.report(ISSUE_2, ...)
}

Everything works like a charm in both Gradle and IDE. The issue occurs on attempt to unit test the logic.

I wrote the following two tests:

@Test
fun test1() {
    val layout = xml(...)

    lint()
        .customScope(Scope.ALL_RESOURCES_SCOPE)
        .files(layout)
        .issues(ISSUE_2)
        .run()
        .expectClean()
}

This one passes as ISSUE_2 requires another scope - it is simply not run.

@Test
fun test2() {
    val layout = xml(...)

    lint()
        .customScope(Scope.ALL_RESOURCES_SCOPE)
        .files(layout)
        .issues(ISSUE_1)
        .run()
        .expect("some_output")
}

And this one fails! But it fails not because of the wrong expectation. No, it fails, because the following assertion in the LintDriver class:

fun analyze() {
    //noinspection ExpensiveAssertion
    assert(!scope.contains(Scope.ALL_RESOURCE_FILES) || scope.contains(Scope.RESOURCE_FILE))
    ...

What is the correct way to verify issue/detector against the Scope.ALL_RESOURCE_FILES then?
