Tool Tip Custom CSS Not Working

The CSS styles for Tool Tips seem to have changed in this newest version of Shortcodes. Previously, I used the following CSS in the Shortcode > Settings > custom CSS code:

/* Change text style for words linked to a Tooltip */
.su-tooltip {
    color: red;
    font-weight: 700;
}

Which would change the style of the term linked to a tool tip – so readers knew to hover over the term. However, this code no longer seems to work. I have no style change for linked tool tip terms. Can someone provide the code I would need to highlight my linked terms?

As example – in the page the URL goes to, the term “four-fingered gagger” has an associated tool tip. This term used to be bold and green font.

Appreciate all assistance.
