Accordion props

[Alina Lapina]

Suggestion

It could be nice to provide to Accordion header a fallback component (not a simple string) when the title is not fetched yet.

Background

In my project we use Accordion component this way:

<Accordion 
    header={isLoadingVersion 
        ? <Spinner/> 
        : `${origin?.title}`} 
    subHeader={origin.rank}
>

It's not allowed to provide components to the accordion header, it requires a string.
We have to show spinner, while the title downloads.
