Tests that custom events with composed:true from deeply nested shadow DOM components (grandchild → parent → grandparent) correctly reach the grandparent's @event root handler on <template shadowrootmode>. The fixture has 3 components: test-grandparent (listens via root event), test-parent (passthrough), test-child (emits composed event on click). All 4 tests pass — the framework's \ correctly handles composed events that pierce shadow boundaries. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
