Sometimes <a-n> does not work but <a-p> does.

[CapSel]

Describe the bug I have a big C++ code that I can't share. There is a if, then inside range loop declaring a variable, and this variable is used 2 times inside a loop. I can use <a-p> to switch between all 3 references (declaration, 2 uses) of variable but <a-n> works only when cursor is on uses.

I verified that it's not problem with shortcuts - giving command :lua require('illuminate').goto_prev_reference() works like <a-p>, with :lua require('illuminate').goto_next_reference() works like <a-n>.

To Reproduce open big C++ code base... and function with range loop... I can't really narrow it down further. I'm forbidden from sharing the code or what it does.

Note Omitting a minimal init.vim/init.lua/.vimrc will likely result in the issue being closed without explanation.

Output from :IlluminateDebug will see what :IlluminateDebug does tomorrow. I could not find info about debugging before reporting this bug.

Expected behavior behavior of <a-n> should be reverse of <a-p>

I am unable to reproduce. A minimal init.lua and a minimal C++ file is required. There is likely an interaction going on with another plugin since the goto code has no knowledge about declaration/use for references https://github.com/RRethy/vim-illuminate/blob/5eeb7951fc630682c322e88a9bbdae5c224ff0aa/lua/illuminate/goto.lua#L1-L63.
