Lingering red highlight of variables/functions after clicking away

[OliverBeckwith]

When clicking on a symbol: that symbol, and other references of it, change text colour to red (with Macchiato). This colour change then lingers when clicking away from the symbol until you next click on another var or function.

Not seeing this with other themes (both Fleet defaults and other external themes I've added). Can't figure out which setting in the JSON causes this.
