Current tab text not showing on mobile

Not sure if this is a bug or if I’m just doing something wrong, but the text for my current tab doesn’t show up on mobile (on either iOS Safari or Chrome) and only shows on my iPad after hovering. It has a gradient background text clip, which I know some browsers don’t support, but I don’t think that’s the issue. Any ideas?
