@Tag works only if placed on method but not on class

[TimurKasatkin]

Let's us consider following example:

import org.junit.jupiter.api.Tag
import org.junit.jupiter.api.Test

class Test1 {

    @Test
    @Tag("tag1")
    suspend fun testCase1() {
        //...
    }

}

@Tag("tag1")
class Test2 {

    @Test
    suspend fun testCase2() {
        //...
    }
}

If junit5 tests launched with tag tag1, only Test1#testCase1 will run, but not test methods of class Test2.

Environment 1:

• java 11.0.5-BellSoft
• IntelliJ IDEA 2020.3.2 (Ultimate Edition)

Environment 2:

• java 11.0.5-BellSoft
• maven 3.6.3
• maven surefire-plugin 2.22.2

After some short research and debug, I have discovered that both CorounitClassDescriptior and CorounitMethodDescriptior have correct values of getTags() method from org.junit.platform.engine.support.descriptor.AbstractTestDescriptor, but only methods marked by @Tag annotation are ran.
