fix: which-key breaks vim.v.count in visual mode

[nathanzeng]

Reproduction

1. Go to this line (currently 901 in master), and put your cursor on the first '. I marked cursor pos with | |
local parsers = { |'|bash', 'c', 'diff', 'html', 'lua', 'luadoc', 'markdown', 'markdown_inline', 'query', 'vim', 'vimdoc' }
2. Type v]n2]n
   Confirm that 'diff' is selected when in reality 'html' should be selected
3. To confirm this fixes it, checkout this branch and then do the above steps again

Here is the issue where it is reported upstream
