I am no longer able to reproduce this bug

I suspect there have been multiple causes of this symptom over time. One specific cause was fixed by arduino/arduino-language-server#96 and I would guess the other work on the Arduino Language Server fixed some others.

I have not been able to reproduce it ever since I started using Arduino Language Server 0.6.0, which was added to the Arduino IDE build by #738.
