Wrong Attached Buffer

[ZeekDaGeek]

When loading a session with a Vertical Split Qalc will be attached to the wrong buffer.

Reproduce:

1. :vsplit 2, Open any *.qalc file in the left pane
2. Open a random txt file in the right pane.
3. Save the session and close Neovim.
4. Reopen and load the session and the Qalc calculations will be on the right hand side text file instead.

Doing :QalcAtatch on the left pane also doesn't make calculations show up on the left side.

Are you using a session manager plugin? :mksession and :source work fine for me.

I'll admit that I didn't realize that Startify sessions are unique, I thought it was mainly just a tracker for sessions.

I attempted to create a new session and I can't seem to get it to reproduce now.

Here's my broken session:

let SessionLoad = 1
let s:so_save = &g:so | let s:siso_save = &g:siso | setg so=0 siso=0 | setl so=-1 siso=-1
let v:this_session=expand("<sfile>:p")

  let s:wipebuf = bufnr('%')
endif
let s:shortmess_save = &shortmess
if &shortmess =~ 'A'
  set shortmess=aoOA
else
  set shortmess=aoO

I'm trying to play spot the difference and make the new session break, but I can't get it to happen.

[ZeekDaGeek]

I was able to get it to happen again, apparently it's maybe related to how complex the calculations in the Qalc buffer are?

Broken:

Fine:
