Describe the bug
When using x or y axes with a groupId along with a RectAnnotation. If no groupId is set on the RectAnnotation it will not appear as there is no __global__ groupId fallback to determine the correct fallback height.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://codesandbox.io/s/cool-cookies-s8okq?file=/src/App.tsx
2. Notice how toggling the groupId on the RectAnnotation hides and shows

Expected behaviour
When no x or y axis groupId is determinable, it should fallback to the chart dimensions.
