PrimeVue Bug: 点击 Tree 组件根节点 (package)，有时触发 aria-hidden 错误

[zjp-CN]

Blocked aria-hidden on a <button> element because the element that just received focus must not be hidden from
assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the 
inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the 
WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.
