The reactive range of hovering of Markers is larger than the underlining range

Question

In Monaco Editor, Markers allow to underline a text and display a message when hovering over it. But I just realized that the reactive range of hovering is a little bit larger than the underlining range. As a consequence, messages can be confusing when two markers are adjacent.

For instance, I have the following code which can work in the playground.

If I hover on c (or put the focus between b and c, then press Ctrl+K Ctrl+I), both of the two messages are shown. However, at this location, only the message for c is relevant and expected.

Similarly, if I hover on d (or put the focus between d and e, then press Ctrl+K Ctrl+I), both of the two messages are shown. However, at this location, only the message for d is relevant and expected.

Does anyone know whether it's possible to tweak this behavior of markers (i.e., make the reactive range of hovering exactly same as the underlining range)?

monaco.languages.register({ id: 'myLanguage' });

monaco.editor.onDidCreateModel(function(model) {
      var markers = [{
        severity: monaco.MarkerSeverity.Error,
        startLineNumber: 1,
        startColumn: 3,
        endLineNumber: 1,
        endColumn: 4,
        message: 'need to correct c'
      },
      {
        severity: monaco.MarkerSeverity.Error,
        startLineNumber: 1,
        startColumn: 4,
        endLineNumber: 1,
        endColumn: 5,
        message: 'need to correct d'
      }];
      monaco.editor.setModelMarkers(model, 'myLanguage', markers);
});

var ed = monaco.editor.create(document.getElementById("container"), {
    value: "abcdefg",
    language: "myLanguage",
    lightbulb: { enabled: false },
});
