Problems with font on Cyrillic dictionaries

[YukiNagat0]

Description
After update, on default font (void or "sans-serif") cyrillic dictionaries went crazy. Before addition of Font customization (#1184) entries were displayed correctly.

Proposal:

1. Return prior default font
2. Add an option to change font of the specific dictionary (e.g. set a global/base font for all dictionaries and set a different font for the specific dictionaries as exception)

Reproduced on the 7.15 release, it appears to be fixed in the 7.22 development release likely due to #1231.

Having an empty string as the font (in releases after 7.15) should be the same as before the font option was added (the font will be 'Helvetica Neue', Helvetica, Arial, sans-serif).

Fixed in 24.7.24.0 (stable)
