CodeNav does not respond, and refresh does not work when too many classes in a file

[ToMakeSense]

It seems that because of too many classes in a source code file, the panel of CodeNav cannot fresh(CodeNav still displays the results of the previous open file, it can't seem to show scrollbar automatically).

Tricky details
If you try to fold the code multiple times CTRL + M, L, The CodeNav window will be triggered to display the beginning part of the source file. However, if the file is opened for the first time, CodeNav does not respond, the CodeNav window cannot be activated and displayed, even if the code is folded multiple times. in this situation, unless you temporarily remove some blocks of code to activate the CodeNav window, then press CTRL + Z and restore the code, to get the CodeNav window activated.

Wow sounds weird!

How many classes are in your file? Can you share the file?

CodeNav should show a scrollbar for long files:
