Previously, CommandBar's inline bar wasn't bootable within the shadow DOM, and themes would not apply correctly. Now the inline bar is fully bootable within the shadow DOM, ensuring proper functionality and theme compatibility.
The update also includes improvements to the CSS structure to enhance compatibility with other web frameworks (e.g., StencilJS, which uses the shadow DOM), making integrating with other applications and frameworks easier. Overall, this update provides a more seamless and efficient user experience when working with CommandBar's inline bar.
