[SidePanel] Moving the Header down after it's finished the open animation.

Since this is happening in the storybook too, I'll post the link to the storybook here.

As you can see from the screenshot. It's moving the title header section down and hiding a lot of data behind it.

I inspected and removed some elements from the header, this is the content it's hiding.

For my case, it's hiding our tab window

Workaround: Set animateTitle={true}
