That is a confirmed kernel bug that I've been told by kernel dev will be fixed,
it's written in the test commit message as well:

commit 5ffb23e2c051c718814515527275e92a8d3155e0

    syscalls/statx04: Add new test.

    This test will check if statx() reports attribute flags by adding
    FS_COMPR_FL, FS_APPEND_FL, FS_IMMUTABLE_FL and FS_NODUMP_FL to a
    direcotry and checks that the flags are reported correctly and also
    tests a directory with no flags.

    The test is executed against all filesystems, since most of the kernel
    code that implements this functionality is filesystem specific.

    * The ntfs3g fuse driver reports wrong errno for unimplemented ioctls()
      EINVAL while every other filesystem reports ENOTTY correctly

    * The test fails for ext2 filesystem mounted by kernel ext2 driver,
      which is confirmed to be kernel bug that will be fixed later on
      ^
