I want to have the effect like this:

So I use editor.deltaDecorations() to edit inline css class. this is my code

var content = [
    'xxx line 1 xxx',
    'xxx title xxx',
    'xxx line 3 xxx'
].join('\n');

var editor = monaco.editor.create(document.getElementById('container'), {
    value: content,
    language: 'plaintext'
});

var decorations = editor.deltaDecorations(
    [],
    [
        {
            range: new monaco.Range(2, 4, 2, 10),
            options: {
                inlineClassName: 'myclass'
            }
        }
    ]
);

css

.myclass {
    color: red;
    font-size: 50px;
}

The result is

Monaco editor changed the font size, but didn't recalculate the height of line，how to solve this problem? help !
