File changes in symbolic linked directories are not reflected

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Annotations, Type Checking, Completion, Diagnostics/Syntax Checking, Hover, Libraries

Expected Behaviour

When the content of a file within a directory which is a symbolic link changes, the language server should reflect the changes in, e.g., the code completion, hover, or diagnostics.

Actual Behaviour

The changes are not reflected, i.e., the code completion, hover information, or diagnostics as examples are not updated.

Reproduction steps

1. Open a workspace which contains a directory which is a symbolic link.
   Example:

   

   The following content of common.lua is loaded:

   ---@param p1 string
   local function t1(p1)
   end
   
   ---@param p2 string
   local function t2(p2)
   end
   
   return t1;

2. Change the content of common.lua with an external program without opening common.lua in VSCode, e.g., change the return to return t2;. For t in A.lua, t1 is still shown.

3. Open common.lua in VSCode. Now, in A.lua, t2 is shown for t.
   

Alternative:

1. Open the workspace with the symbolic linked directory and the target directory as a second workspace.
   Example:
   
2. Open common.lua in the actual directory, and change something, e.g. the return to return t2;.
3. t in A.lua still shows the information about t1. If common.lua in the symbolic linked directory is opened, t shows t2 on hover.

Additional Notes

I am not sure if this behavior is intended or a bug. So, feel free to close this issue if the behavior is intended.
