No "{tag_name}" element in scope but a "{tag_name}" end tag

Error message

No "{tag_name}" element in scope but a "{tag_name}" end tag seen

What it means

HTML parse error: an end tag (e.g. </form> or </p>-class tags) was seen but no corresponding element exists in the required scope on the stack of open elements, so there is nothing to close. The tag name is embedded in the message; recovery follows the spec (ignore or synthesize the element).

Solutions

1. Remove the stray end tag
2. Add the matching start tag or fix earlier structure so the element is in scope
