Hello, thanks for the awesome plugin.

If I have several popups rendered in a Layout, and I want to get their text content before they are closed via normal Vim methods (for instance if someone uses :q to close the layout) how could I do this?

We have tried to get the text content by referencing the popup.bufnr for each, but this does not work. For instance:

  popup:on(event.BufUnload, function()
    -- Get the buffer text here via popup.bufnr
      local lines = vim.api.nvim_buf_get_lines(popup.bufnr, 0, -1, false)
  end)

This does not work because the popup is already removed by the time these events fire, and we see an error: Invalid buffer id: 11
