Operating system/version

Arch

How to reproduce the issue

1. lua vim.opt.scrolloff = 7.
2. :call setqflist(map(['/path/to/file1', '/path/to/file2'], {_, val -> {'filename': val}})).
3. copen and select the first file.
4. now in the first file, copen and select the second file.
5. now go back to the first file with :bn or <C-^>.
6. lua vim.print(vim.opt.scrolloff._value) should be zero.

Expected behavior

vim.print(vim.opt.scrolloff._value) in the first file should be 7.

Actual behavior

vim.print(vim.opt.scrolloff._value) in the first file is zero.

It seems like this condition doesn't do as it should:

nvim-bqf/lua/bqf/magicwin/handler.lua

Lines 226 to 232 in e20417d

	if scrollOff ~= 0 then
	-- turn off scrolloff to prepare for guessing bwrow
	vim.wo[winid].scrolloff = 0
	cmd(('au BqfMagicWin WinLeave * ++once %s')
	:format(([[lua vim.schedule(function() if vim.api.nvim_win_is_valid(%d) then vim.wo[%d].scrolloff = %d end end)]])
	:format(winid, winid, scrollOff)))
	end

So currently, I've commented out vim.wo[winid].scrolloff = 0 line and it's fixed. But since I don't know what magic window is exactly, I prefer to wait for someone else to fix this.

magic win behavior is similar to that of the splitkeep option added on 2022-10-06. This will be fixed later.
