Actual behavior

When I had the f-string like print(f"{}") typed in, the parameter hint keep shows up even when the cursor is outside of the function call.

Expected behavior

The parameter hint should disappeared automatically when the cursor is moved outside the function call.

Steps to reproduce:

• Turn on the parameter hint if you didn't
• Type something like print(f"{}") and move the cursor outside of the ) and you will see what's happening
