Font size dropdown regression

[Keith Curtis]

Hi;

Sorry for causing bug:
http://cgit.freedesktop.org/libreoffice/core/commit/?id=8138c07b984ba1654483b4dc3488820ca4deaaca
https://bugs.freedesktop.org/show_bug.cgi?id=73051

I'm not exactly sure what is going on, but on my HiDPI machine with
the 30 value I can fit 7 digits! Too many is better than too few but I
had tried to improve.

I have been worried about that change so now that it is reverted, I
don't have to anymore:
