Change the type of the 'header' property on TabPanel

Current behavior
Although it works we get a console error when instead of a string we use a component on the header.
Can you change the propTypes ?

<TabView>
    <TabPanel header={<MyComponent/>}>
        <MyContent />
    </TabPanel>
</TabView>

Just the leftIcon / rightIcon and a string for header is not flexible enough. Having the ability to send a custom header is very important for us.

If we use the <TabMenu /> and not the <TabView><TabPanel /></TabView> then we don't have the error but we lose functionality.
