Code folding causes Follow Symbol to scroll to wrong place

Steps to reproduce

1. Open the attached source file.
   I believe the key thing about this file is that there are some lambdas inside a loop inside a function.
2. Ensure that Animate navigation within file is turned on (under Tools > Options; Text Editor > Display).
3. Make sure your window size is such that about 60 lines of code are visible in the viewport at once.
4. Scroll down to FunctionC and fold up the 5 lambdas.
5. Scroll down to FunctionD and control+click on the call to FunctionC inside it.

Result: although the text cursor moves to FunctionC, the viewport does not scroll to show the cursor. Instead, it scrolls too far and FunctionB is visible.
