Safari still requires -webkit-mask-image. Always include both the prefixed and unprefixed versions, or use an autoprefixer in your build pipeline.

Using mask-image on elements with overflow: visible

Masking can cause unexpected results with overflowing content. Set overflow: hidden on masked elements or ensure the mask covers the full content area.
