Can’t define default code block width in % or em

Hi,

first of all thanks for the very useful plugin!

In the plugin settings it says for default code block width:

Default code block width. Integer means pixels, also you can specify em or % suffix. Could be omitted to use whole width.

However, if I try to put anything else than plain numbers (e.g. 80%) I get an error “Please type a number” (translated from German). Seems like the input field doesnt allow “em” or “%” to be specified?

Thanks,
