HTML component highlights random blocks in pale blue on hover

I'm rendering some custom HTML using the HTML component, and noticed that on mouse hover, random sections of my html are being highlighted. Does anyone know why this is, and how it can be removed? I saw that there is a CSS entity tied to it called --markdown-highlight, and when it's disabled in Chrome dev tools, it turns off the highlighting. However, I'm not sure how to disable this programmatically via retool.
