Hi,
The feature was designed when google suggestions did not use a drop-down feature to select from multiple suggestions. Hitting the right arrow key will complete the suggestion. This is due to a rework some time later this year.
I tried a few longer phrases, but it seemed all right on my end: https://i.imgur.com/aUnlEh6.png
I’m not sure if the issue is resolved, or if it was temporary. Let me know if it’s something else.
