Document symbols fail for large markdown document

[Jeangowhy]

Does this issue occur when all extensions are disabled?: Yes

VS Code 有个问题，渲染大文档时，比如 10MB 尺寸的 Markdown，它渲染流程会从头处理到用户浏览
的位置，所以当界面宽度调试时，比如侧栏面板切换显示时、窗口伸缩时，就会导致卡死，因为 VS Code
在做“无用”功。反观 Sublime Text 或者 Vim 就不会这样低能，只渲染视图缓存区间直接避免此类问题。

此问题出现在禁用所有插件状态下出现。只要文件标签不是当前编辑中处于活动状态（TextEditor Hidden），此问题就不会出现。

• OS Version: Windows_NT x64 10.0.18362

Steps to Reproduce:

1. Open a markdown file big enough, such as 10MB.
2. Resize VS Code window, or toggle sideba when the markdwon file is active.

The bigger of file the longger time to wait, if you resize the TextEditor render area.

I am able to resize the window with no problems
