How can the units for font size be standardized?

I am working on Writer document based on the LibO default template

I wanted to change quickly the font size for Heading1 and Heading2 in the style window. I suddenly saw the the style window for Heading2 showed the font size in the normal unites 10, 11, 12, 14 etc whereas for Heading1 the font size was shown in % .

How can I get the same, prefered normal units displayed in both style windows?

… or is this a bug?

This is not a but, it’s a feature. What you need to do is just type your number WITH unit, eg 14pt

To see why this is useful, read this question, that question is the exact opposite: Scale font size for all text[Feature Request Submited][Closed]

I expected a bug… but got a nice feature. Thanks for the good news!
