Regarding search engine limitations, there are these rules for sitemaps:

Any Sitemap file is limited to 50MB (uncompressed) with a maximum of 50,000 URLs.

But if you pass this number, no new sitemap file gets created.

With having 50002 web contents with certain display page

Expected behavior:
You get two sitemap links in your sitemap index (sitemap.xml) one with 50k URLs and another one with 2 URLs

Actual behavior:
You get one sitemap link in your sitemap index (sitemap.xml) with 50002 URLS
