Selecting two audio clips offered "Group selection", which is the layout grouper: it wraps the members in a positioned <div> at their bounding box, rebases each child's left/top against that origin, and adopts the topmost member's z-index. None of that means anything for audio. An <audio> clip has no box — offsetWidth/Height are 0 — so the wrapper came out `width: 0px; height: 0px` with inline left/top written onto elements that are never laid out, and the composition gained a <div> standing for nothing audible. Confirmed against `wrapElementsInHtml` directly: it matched and wrapped, producing exactly that. Refused in `handleGroupSelection`, which is where the G shortcut also lands — a hidden button cannot gate a keystroke. The panel withholds the button as well, so the refusal is not the first the author hears of it. The message names the alternative rather than only declining: audio's answer to "these clips belong together" is an <hf-audio-group> bus, which the timeline's own FX pointer already creates. A mixed selection is refused too — the wrapper would take the audio in with the rest. `isAudioDomElement` sits beside `isAudioTimelineElement` and delegates to it, so the selection layer and the timeline cannot drift into disagreeing about what counts as audio. Six tests across both entry points, each mutation-checked. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
