nvim-autopairs is breaking `i_CTRL-G_j` commands

[polirritmico]

Description

The plugin is breaking the <C-g>j/<C-g>k behaviour in insert mode.

From :h insert-index:

i_CTRL-G_j CTRL-G CTRL-J line down, to column where inserting started i_CTRL-G_j CTRL-G j line down, to column where inserting started

But if the cursor begin the edit inside a pair, then <C-g>j is not moving to the column where inserting started.

Mapping bug

No response

Steps to reproduce

1. Open a new file with nvim-autopairs enabled.
2. Write this content:

1. ""
2. ""

3. In normal mode move the cursor inside the first " pair.
4. i and type test()
5. Now, still in insert mode, press <C-g>j
6. The cursor move outside the second " pair.

---

Expected behaviour:

1. Open a clean nvim instance: $ nvim --clean foo Repeat steps 2 through 5.
2. The cursor move inside the second " pair.
