What
Claude Code checks mockup files before using them. That checker now refuses an HTML element placed inside SVG (a format for drawings made of code). The message says the element is not an SVG element, and that browsers and the checker read what follows it differently.
Why
When a browser and the checker read the same markup in different ways, content could slip past the checker. Refusing this pattern closes that gap.
