[Bug/Docs] Close function signature when leaving function

[omeyenburg]

The function signature remains for me with the default config when I leave the function in either of these ways:

• I close the function with a bracket ")"
• I navigate to a different line using the arrow keys (skill issue on my side... I'm going to take the arrow keys out of my keyboard)

I could resolve the first problem by adding always_trigger or extra_trigger_chars to the opts:

• always_trigger = true
• extra_trigger_chars = {"(", ",", "=", ")"}

But I think this should be part of the documentation if not default (unless this problem only occurs for me due to my config).
Is this intentional/usual behaviour?
