Bug - Page/Drawer - PageSection in DrawerBody has an incorrect height

Describe the problem
I am trying to build a page, which has several clickable cards on it, and when you click on the card, there will be a drawer panel shown on the right side. However, when implementing this, I find some issues with the page height. See the example below for the details.

How do you reproduce the problem?
I created a code sandbox example here: https://codesandbox.io/s/vigorous-bohr-ydpp8d?file=/index.tsx
I try to put a drawer in a Page component and set the PageSection in the DrawerContentBody, however, the DrawerContentBody is not flex display, which will make the grey background page section not take up the entire page height. So I use the Flex layout provided by PatternFly. However, another bug comes, the page section will take up more height than it should take, which causes the page to scrollable.

Expected behavior
The page section will take up the full page height when there is no enough card, and will be scrollable when there are a lot of cards.

Is this issue blocking you?
I can create some custom styles to avoid this. However, I still want to use only PF to build the application, avoid making any custom styles.

Screenshots

What is your product and what release date are you targeting?
ODH/RHODS

Any other information?
I am not sure whether it's permitted to put PageSection into DrawerContentBody by design. If not, what's the workable way to implement this feature? Is there any component that can provide me with a grey background on which I can put a lot of cards?

Comienza con la reproducción de CodeSandbox en index.tsx y compara el comportamiento del diseño de Page, PageSection, Drawer y DrawerContentBody. Verifica el resultado tanto con pocas como con muchas tarjetas. Se considera terminado cuando la sección ocupa la altura disponible de la página sin crear desplazamiento no deseado, y sigue siendo desplazable cuando el contenido de las tarjetas supera la altura disponible.
