I have a pretty standard header using the Pro theme. I just updated to WordPress 5.3 and Pro 3.1.1. I also updated the Yoast Plugin and “Hide SEO Bloat,” but made no other changes. After doing all that, the icon for my search modal is now cutoff in the header:

When I attempt to edit the header, the whole area just displays an error that says:

There’s nothing custom added on the header, so the HTML error isn’t mine. Can you help, please?
