getPageBreadcrumbs() result does not include collection parent page

Description

If the child page belongs to a "collection" (database) parent page, the result of getPageBreadcrumbs(recordMap, childPageId) does not include that parent database page.

Notion Test Page ID

f9ee16bddeac4ce58c3d3ce8055f78a9. This "Main Page" belongs to a "Test Db" collection page.

• The breadcrumbs of notion.site page: Notion Dev Site / Test Db / Main Page
• The breadcrumbs of getPageBreadcrumbs() : Notion Dev Site / Main Page

Possible Fix

To fix this problem, getBlockParentPage could be changed

export const getBlockParentPage = (
  block: types.Block,
  recordMap: types.ExtendedRecordMap,
  {
    inclusive = false
  }: {
    inclusive?: boolean
  } = {}
): types.PageBlock | null => {
    // ... omitted

    if (parentTable === 'collection') {
      currentRecord = recordMap.collection[parentId]?.value
    } else {
      currentRecord = recordMap.block[parentId]?.value

     // -----> changed from: if ((currentRecord as types.Block)?.type === 'page') {
      if ((currentRecord as types.Block)?.type === 'page' || (currentRecord as types.Block)?.type === 'collection_view_page') {
        return currentRecord as types.PageBlock
      }
    }
  }

  return null
}

Start with getPageBreadcrumbs(recordMap, childPageId) and the linked packages/notion-utils/src/get-block-parent-page.ts. Trace how collection parents and collection_view_page records are handled, using the supplied Notion page ID as the reproduction case. Done means the breadcrumbs include Notion Dev Site / Test Db / Main Page for that child page.
