inconsistent display of the font size value

1. Go to OpenOffice > Preferences > OpenOffice Writer > Basic Fonts (Western)
2. Change the Default Font Size to 2.1 and Save

The displayed Default Font Size has been correctly changed to 2.1 in the following fields:
- OpenOffice > Preferences > OpenOffice Writer > Basic Fonts (Western))
- Properties > Text > Font Size

but the Default Font Size in the main Formatting toolbar above the document has been changed to 2 (see attachment).

This behaviour takes place only for decimal values for which an approximation is expected to take place. For example, 2.1, 2.3, 2.6, ...

For the other cases (e.g., 2, 2.2, 2.4, 2.5, ...) this behaviour does not take place (i.e., the saved font size value is consistent across the different displays).

This issue seems to related to the two following existing issues involving consistency in the display of decimal font size values:
