Steps to Reproduce:

1. Write 1001 lines of hello to hello.txt. Open it with VS code.

   for ((i=1; i<=1001; i++)); do
       echo "hello" >> hello.txt;
   done

2. Select hello at line 900, and press Command/Ctrl + F.

   

   Wrong current index in find widget if the number of matches > 1000:
   899/1001 (Wrong, should be 900/1001)

3. Delete hello at line 1001. Then select hello at line 900, and press Command/Ctrl + F.

   

   No issue if the number of matches <= 1000:
   900/1000 (Correct)
