Snippet 'fori' cannot jump to the `type` placeholder

[liuyehcf]

snippet fori is like this:

    for (int i = 0; i < count; i++) {

    }

It has four placeholders, which respectively are count、0、i++、int of the above case.

When I use coc-snippets(3.1.6) to drive the snippet, it only iterate the first 3 placeholders.

And when I change to 'SirVer/ultisnips', it works fine for iterating the 4 placeholders.

And for lower version of coc-snippets, maybe 2.8.x(not for sure, but must be 2.x), it also works fine.
