Russian: wrong display of the number in Russian language

[afuno]

ru:
  general:
    pluralization:
      subtopic:
        one: 1 подтема (1)
        few: "%{count} подтемы (2)"
        many: "%{count} подтем (3)"
        other: "%{count} подтем (4)"

. = t('general.pluralization.subtopic', count: '21')
. = t('general.pluralization.subtopic', count: '22')
. = t('general.pluralization.subtopic', count: 21)

Output:

21 подтем (4)    # ok - it is a string
22 подтем (4)    # ok - it is a string
1 подтема (1)    # not ok

Lines 18 to 22 in 86942a8

	mod10 = n % 10
	mod100 = n % 100
	if mod10 == 1 && mod100 != 11
	:one

mod10 = n % 10

The variable mod10 has a value of 1. This is a problem.

I don't see a problem here:

1 - одна подтема
11 - одинадцать подтем # probably here is the problem, but everything is ok with value 1
21 - двадцать одна подтема
31 - тридцать одна подтема
