Auto wrapping too much when using non-monospace font

Testing #19061

Have the following snippet in an editor buffer, with editor.fontFamily set to Arial and editor.wrappingColumn set to 0.

/**
 * @param {Array<string>} [plugins=['defaults']] - plugins to enables @param {Array<string>} [plugins=['defaults']] - plugins to enables @param {Array<string>} [plugins=['defaults']] - plugins to enables @param {Array<string>} [plugins=['üdefaults']] - plugins to enables plugins to enablesplugins to enablesplugins to enablesplugins to enablesplugins to enablesplugins to enablesplugins to enablesplugins to enablesplugins to enablesplugins to enables
 */
define(['modules/interface'], function (i) {
  console.log(i);
})

You'll notice the editor is wrapping more than it should:
