Expected behavior

A proper table should be visualized

Actual behavior

The plain-text version of the table markdown is shown.

| Aspect | Plain Vanilla JS | Web Components | |--------|------------------|----------------| | Setup | Find a DIV, attach handlers directly | Define a custom element class, register with customElements.define() | | HTML Usage |

+ initTagManager('#myTags') | | | Style Isolation | None—CSS can bleed in/out, must use unique class names | Shadow DOM provides full encapsulation | | Reusability | Copy/paste JS + CSS, call init function | Just use the HTML tag anywhere | | Form Integration | Manually create/update hidden input | Same, or use ElementInternals API | | Dependencies | None | None | | Browser Support | All browsers | All modern browsers (IE11 needs polyfill) | | File Structure | Separate JS + CSS files, or inline | Single self-contained JS file | | Initialization | Explicit: TagManager.init(element, options) | Automatic: element self-initializes when added to DOM | | Multiple Instances | Must call init for each instance | Just add multiple tags | | Configuration | Pass options object to init function | Use HTML attributes: | | Event Handling | Custom callbacks or manual event dispatch | Native CustomEvent dispatch, use addEventListener | | Cleanup | Manual: must track and remove listeners | Automatic via disconnectedCallback() | | Learning Curve | Low—standard DOM manipulation | Medium—must learn lifecycle callbacks, Shadow DOM | | Debugging | Straightforward DOM inspection | Shadow DOM adds a layer in DevTools | | Framework Compatibility | Works anywhere with minor integration | Works anywhere as native HTML element | | Code Size | Minimal boilerplate | ~20-30 extra lines for class structure | | Attribute Reactivity | Manual: watch for changes yourself | Built-in: attributeChangedCallback() | | Semantic HTML | Generic with classes | Custom element name conveys meaning |

Additional information

No response

No source file, test, or entry point is named. First reproduce the issue in Eclipse using the reported Copilot plugin version and table prompt, then trace the plugin's Markdown rendering path. Done means Markdown tables are displayed as formatted tables rather than plain text.
