The speaker saves the day on wine-in-grocery-stores:

The speaker can vote on any of the committees. And for the first time this year, Harwell chose to do so. She says it’s time to find a compromise that would still be agreeable to the state’s 600 liquor stores, which are the only places wine can be sold now.

“We don’t want to hurt those liquor stores, and we want to do everything we can to make this as palatable to them as possible. This brings everyone to the table to discuss it.”

In the American system, the Speaker is a partisan position — leader of the House's majority party. But in Westminster systems, the Speaker plays a more neutral role (typically standing for re-election with the label of "The Speaker" rather than a specific party).

In the case of ties, the Speakers in those countries follow something called "Speaker Denison's Rule." In short, "The principle is to always vote in favor of further debate, or, where no further debate is possible, to vote in favor of the status quo." In this case, Harwell's vote kept the bill alive for further debate. I've no idea if she knew was following the grand tradition of Speaker Denison, but she did nonetheless.
