Don't collapse bundles and bundled groups after dismissing a child

The old code would ignore bundles in renderingSummaries and therefore
collapse them with setGroupExpanded. Also this code only checked
for the first child layer but now with bundled groups we need to search
recursively such that bundled groups are also present in
renderingSummaries.

Fixed: b/417669266
Test: Manually tested dismissing children in bundles and children of
      bundled groups.
