Thousands of DOM Elements?

HI Christian,
thanks for your answer on https://www.drupal.org/project/geolocation/issues/3204158, im sorry to reopen ist, because i realized it was closed before.
Can you tell me what is the reason for line <div data-views-row-index="0">...</div> and/or can get rid of them, because when I delete them from the DOM with Chrome DevTool the map works without any problem and I can't find similiar DOM-Elements in other leaflet (plugins) so far.

And @performance: Google Speedtest complains about to many DOM-Elements an tells me: A large DOM tree can slow down your page performance in multiple ways:

• Network efficiency and load performance:: A large DOM tree often includes many nodes that aren't visible when the user first loads the page, which unnecessarily increases data costs for your users and slows down load time.
• Runtime performance: As users and scripts interact with your page, the browser must constantly recompute the position and styling of nodes. A large DOM tree in combination with complicated style rules can severely slow down rendering.
• Memory performance: If your JavaScript uses general query selectors such as document.querySelectorAll('li'), you may be unknowingly storing references to a very large number of nodes, which can overwhelm the memory capabilities of your users' devices.

Especially on mobile i experience these problems.
Thanks for your time and answer in advance!
