Multiple Pinned headers should work within a SliverMainAxisGroup #155758
Description
Steps to reproduce
Put multiple PinnedHeaderSliver in a SliverMainAxisGroup widget
It looks like this issue is talking about the same use case, but it has been closed without further investigation.
Expected results
All the pinned widgets should be pinned to the top of the scroll view.
Actual results
Only the first pinned widget is pinned to the top of the scroll view.
