The isBold() and isBold(offset) methods of Class Text return null instead of false when parsing non-bold text.

The documentation for isBold() states that the return value is of Boolean type: "whether the text is bold, or null if the element contains multiple values for this attribute".

Similarly, the documentation for isBold(offset) states that the return value should also be of Boolean type: "The bold setting".

So, according to the documentation, null should only be returned when an Text element contains both bold and non-bold characters.

To reproduce:

1. Create a new Google Docs document containing just the word 'test' without any formatting applied to it.
2. Go to Extensions -> Apps Script, and copy/paste the following Apps Script code:

function myFunction() {
  const doc = DocumentApp.getActiveDocument();
  var body = doc.getBody();
  var paragraphs = body.getParagraphs();
  for ( var i = 0 ; i < paragraphs.length ; i++ ) {
    var paragraph = paragraphs[i];
    var text = paragraph.editAsText();
    for ( var j = 0 ; j < paragraph.getText().length ; j ++ ) {
      var char = paragraph.getText()[j];
      console.log(char + ': ' + text.isBold(j));
    }
    console.log(paragraph.getText() + ': ' + text.isBold());
  }
}

3. Click on 'Run' to run the function myFunction() from above.

You should get the following output in the Execution log: Execution log #1

The expected Execution log output is: Execution log #2

Setting/unsetting the Bold property (from within the Docs UI) of either the entire word or parts of it does not seem to have any effect.

The only way to make isBold() return false is to set the Bold property programmatically with setBold() (this is what I had to do in order to obtain the second screenshot).
