| // Sanitizer can produce TrustedHTML as long as its configuration respects sinks guarded by TT. | |
| // (HTML sinks are only guarded because they themselves could bypass restrictions of script.src etc.) | |

| // Sanitizer can always produce a TrustedHTML. | |
| trustedHTML = (new Sanitizer()).sanitizeToTrustedHTML('<div><script>removeme</script>') // yay! | |
| // If Web APIs add new native XSS sinks, they should be added simultaneously to TT and Sanitizer | |
