make tabpage's active window invalid by win_close from other tab

[notomo]

Neovim Version

NVIM v0.6.0-dev+1594-g68f61b167

Operating system/version:

Ubuntu 20.04

Terminal name/version:

wsltty

TERM environment variable

xterm-256color

Installation

build from repo

Steps to reproduce

build/bin/nvim -u NORC +'luafile minimal.lua'

minimal.lua

vim.cmd("tabedit")
local bufnr = vim.api.nvim_create_buf(false, true)
local window_id = vim.api.nvim_open_win(bufnr, true, {
  width = 50,
  height = 10,
  relative = "editor",
  row = 10,
  col = 10,
})

_G._on_win_closed = function()
  vim.api.nvim_win_close(window_id, true)
  vim.api.nvim_tabpage_get_win(vim.api.nvim_list_tabpages()[2])
end
vim.cmd("autocmd WinClosed * ++once lua _on_win_closed()")

vim.cmd("tabprevious | +tabclose")

Vim

N/A (WinClosed event)

Expected behavior

I'm not sure, but I think the following:

• nvim_win_close raises an invalid window id error
• nvim_list_tabpages does not return closed tab id.

Actual behavior

Aborted (core dumped)
