`Alt-f` and `Alt-F` in insert mode didn't reset `;` and `,`

First of all, thank you for making this great plugin. It was more accurate than something like easymotion.

I have a problem when using Alt-f and Alt-F (and probably with Alt-t and Alt-T) in insert mode. I didn't remap Alt-f and Alt-F so it should behave like Esc-f and Esc-F by default (more info :h i_ALT).

Here's an example scenario:

using vim-sneak to find 2-char pattern
edit those text in insert mode and then decided to append on the next occurrence of >
use Alt-f> and then realize that there's one > before the > I want to append
pressing ; (while thinking it will apply to the last f)
and then go to the next vim-sneak 2-char pattern instead of to the last f

I already set g:sneak#f_reset and g:sneak#t_reset to 1, but still no avail.

So, can I disable ; and , without making a new mapping? i mean making a mapping like:

nnoremap ; ;
nnoremap , ,

nmap <expr> ; sneak#is_sneaking() ? ';' : ';'
nmap <expr> , sneak#is_sneaking() ? ',' : ','

would be funny, or maybe I should do something like this:

nnoremap <Plug>Sneak_; <Nop>
nnoremap <Plug>Sneak_, <Nop>

instead? Is there something that I'm missing?

Thank you.
