[bug]: about the mouse drag

[FlameTornado10]

When first drag a random buffer, the reordering works fine. But after one successful reordering, if I choose to drag another buffer, the one that get reordered is not the one I choose latest, but the one that get reordered before. See as this file.

Also, I check the code about mouse drag and figure out one way to handle this.
in the function on_drag in nvim-cokeline/lua/cokerline/hover.lua,
change

    if M.dragging() == current.bufnr or not M.dragging() then
      M.set_dragging(current.bufnr)
      return
    end

    -- dragged buffer
    local dragged_buf = buffers.get_buffer(M.dragging())

to

    if M.dragging() == current.bufnr or not M.dragging() then
      M.set_dragging(vim.api.nvim_get_current_buf())
      return
    end

    -- dragged buffer
    local dragged_buf = buffers.get_buffer(vim.api.nvim_get_current_buf())

seems to eliminate this bug.
