Yes. I test `ങ്ക` via modify [this test](https://github.com/unicode-org/icu4x/blob/cb7e9151356373baac7ebb5f80d3d5c4436b57e0/components/segmenter/src/grapheme.rs#L272-L278) as the following, and `ങ്ക` produces only two grapheme cluster breaks (begin and end).

```
#[test]
fn emoji_flags() {
    // https://github.com/unicode-org/icu4x/issues/4780
    let segmenter = GraphemeClusterSegmenter::new();
    let breaks: Vec<usize> = segmenter.segment_str("ങ്ക").collect();
    assert_eq!(breaks, [0, 9]);
}
```
