Mal-formatted tag at end of template: "${html}"

Error message

Mal-formatted tag at end of template: "${html}"

What it means

Dev-only warning from parseHTML when the parser reaches the end of the template with residual unconsumed html text and an empty tag stack — i.e. trailing content that is neither text nor a well-formed tag, usually a stray '<', malformed closing markup, or an unclosed construct that consumed the rest of the input.

Solutions

1. Inspect the trailing fragment printed in the message and fix the malformed markup
2. Escape stray '<' characters as &lt; if literal text was intended
3. Check for unclosed comments or attribute quotes swallowing the rest of the template
