What happened

A tabbed cell's tabs array had more than one tab declaring selected: true. Only one tab can be active on first render, so the module resolves the ambiguity itself - the last tab in the array that declared it - rather than refusing to mount.

The fix

Mark exactly one tab selected: true, or mark none to fall back to the first tab.

The smallest fix

{ id: 'main', tabs: [{ id: 'a' }, { id: 'b', selected: true }] }  // b is active on first render
