Summary:
When querying an AXTextArea for AXAttributedStringForRange and looking at the AXFont attribute in the returned string, the font reported is always Times New Roman regardless of what the actual font in the document is at that range.

Steps to reproduce:
1. Open Writer
2. Type some text into it
3. Select all text (Cmd+A)
4. Change its font to "Helvetica"
5.a. Query the AXAttributedStringForRange parameterized attribute of the corresponding AXTextArea and look at the AXFont value
or
5.b. Turn on VoiceOver (Cmd+F5) and press VO+T to hear textual attributes

Actual results:
5.a.: The dictionary contains these keys with these values: {
    AXFontFamily = "Times New Roman";
    AXFontName = "TimesNewRomanPSMT";
    AXFontSize = 12;
    AXVisibleName = "Times New Roman";
}
5.b.: VoiceOver says "12 point Times New Roman"

Expected results:
5.a.: The dictionary contains these keys with (approximately) these values: {
    AXFontFamily = "Helvetica";
    AXFontName = "HelveticaPSMT";
    AXFontSize = 12;
    AXVisibleName = "Helvetica";
}
5.b.: VoiceOver says "12 point Helvetica"
