Numbers are white colored on white background when selected in galculator

When I select the number in the result field it disappear.

How to produce:
1. Type some number
2. Try to select the number from the result filed

Workaround:
Change background color to grey (edit >> Prefrences >> Display)

Reason behind the problem:
When the number is selected it is colored white so it does not appear on the background
