当存在split窗口行为时，有时会出现 浮动窗口页面错误

[yaocccc]

个人配置情况： hi CocExplorerNormalFloat ctermbg=none guibg=none

coc-config: "explorer.presets.floating.position": "floating", "explorer.presets.floating.floating-width": 80, "explorer.presets.floating.floating-position": "center",

启动命令：:CocCommand explorer --preset floating

复现过程： :CocCommand explorer --preset floating :CocCommand explorer --preset floating :split :bd ::CocCommand explorer --preset floating
