…ldren GTS component invocations can appear as <this.Foo>, <@foo>, or <ns.Foo> in addition to PascalCase. The rule's isComponent() check was too narrow, so children of headings using these forms were not recognized as content and the heading was falsely flagged as empty.

What's broken on
masterisComponentonly considers PascalCase tags orFoo::Barnested-component syntax. It misses three valid GTS component invocation forms per the template tag format guide:<this.Heading>(class-scoped component reference)<@heading>(argument-passed component)<ns.Heading>(dot-path re-export)When one of these appears as the only child of a heading, the rule walks the child list, fails to identify it as a component, and reports the heading as empty.
Fix
Extend
isComponentwith three additional conditions:tag.startsWith('this.'),tag.startsWith('@'),tag.includes('.'). All three are component forms that cannot be HTML elements in any mode (HTML doesn't allowthis./@/.in tag names).Test plan
<h1><this.Heading />,<h2><@heading />,<h3><ns.Heading />) all fail on masterCo-written by Claude.
