The bottom border is gone after I press r or d

[rockyzhang24]

After I press d or r to open the diff window, the bottom border is not displayed. I noticed that its height is too big and it covers the statusline.

My git-messenger config:

local g = vim.g

g.git_messenger_no_default_mappings = 1
g.git_messenger_always_into_popup = 1
g.git_messenger_popup_content_margins = 0
g.git_messenger_conceal_word_diff_marker = 0
g.git_messenger_floating_win_opts = {
  border = 'single',
}

Neovim version is 0.9.

A short demo was attached below.
