Join Waitlist CTA has text disappearing in WebKit

Under certain conditions, the text content seems to disappear (macOS 15, Safari 18):

… usually on navigation somewhere and back, or leaving and coming back via the site tab bar. Sometimes the text appears just on hover, sometimes on window repaint (like changing its size or adding more tabs), sometimes by leaving the window in background and then switching back to it.

Wondering if that's something webkit-mask—related on the pseudo, or a font paint issue using that styling.
