Relative link does not open respective to the current file

[mquhuy]

Hi. I've started using this today, and I found this issue, which might be a bug. I'm using the default config with latest version.

Here is how to reproduce it

mkdir -p test/foo1 test/foo2
cd test
touch foo1/index.md
echo "[child](child.md)" > foo2/index.md
echo "This is foo2 child" > foo2/child.md
nvim

• open foo1/index.md(*)
• open foo2/index.md
• Try to access the link to foo2/child.md
• Instead of arriving to foo2/child.md, we get to foo1/child.md

• You would get to the expected file if you didn't open foo1/index.md in the first place.
