With 0.91, when selecting a value in the font size widget, the widget always shows exactly the selected value.
Now with 0.92, Inkscape tends to show a value with decimals, which prevent the scroll wheel from working.
On my Xubuntu 16.04 computer, the widget only shows rounded values if you select a very big size (72 or 144), and in that case, the scroll wheel works as expected (until you reach 64...).
Note that if you enter a value that is not in the list (with round values like 7 or 15, or decimal values), the application has exactly the same behavior, even with 0.91.
