When using millimeters as the unit of measurement, size values typed into Position and Size panel do not remain as typed and are instead changed to a near value. For example, a width value of '8' or '8.00', whether typed or arrived at through the spinner buttons, will change to '7.87 mm' if the object is deselected and then selected again.
Steps to Reproduce:
1. Draw a horizontal line object.
2. Make sure that the line object is selected. If not, then select it.
3. In the Width field on the Position and Size panel, type '8.00' or just '8'
4. Change field focus.
5. Deselect line object, then reselect.
Width field contains '7.87 mm'.
Width field should contain '8.00 mm'.

Hmh, noticed there is an older report (which I had confirmed in 2016).
