The `_contentHeaderTopInset > _contentHeightSurplus` check in `MDCBottomDrawerContainerViewController`'s `cacheLayoutCalculationsWithAddedContentHeight:` function was erroneously evaluating to `true` when presenting content:
- in full screen
- with no header
- with the content's height being equal to the available height
Because of how `_contentHeightSurplus` is calculated, it was almost (but not quite) equal to `_contentHeaderTopInset`, which was causing the function to infinitely recurse.
This PR also adds an example that demonstrates the issue. To reproduce:
1. Open MDCDragons
1. Navigate to the "Bottom Drawer No Header Less Content" example
1. Rotate the phone/simulator to landscape
1. Show the bottom navigation drawer by tapping on the menu icon
Expected:
The bottom drawer is displayed.
Actual:
The `cacheLayoutCalculationsWithAddedContentHeight:` infinitely recurses and the app crashes due to stack overflow.
Closes#7633
