WordPress Importer: cannot import iframes

My WP blog had many OSM maps within iframes.
I exported from the blog to an .xml .
This is an example as the .xml looks like:

iframe start: src="https://umap.openstreetmap.fr/de/map/2019-02-05_feringasee_5km_292148?scaleControl=false&miniMap=false&scrollWheelZoom=false&zoomControl=true&allowEdit=false&moreControl=true&searchControl=null&tilelayersControl=null&embedControl=null&datalayersControl=true&onLoadPanel=undefined&captionBar=false" width="100%" height="500px" frameborder="0" allowfullscreen="allowfullscreen" iframe:end
link start: a >Vollbildanzeige (rechte Maustaste) :link end
(I want to show the source code here, therefore I use start / end, I hope you understand).

Later I re-imported from this .xml with plugin “WordPress Importer”.
But only this part of .xml is imported:
link start: a >Vollbildanzeige (rechte Maustaste) :link end
without iframe.

Look the example:
https://notizen2019.netzjahre.com/2019/02/feringasee-05/
No iframe is here, only the link text is shown:
“Vollbildanzeige (rechte Maustaste)” (German text like: full screen display (right mousekey) )

Meanwhile I restored some iframes manually, it looks like if iframe is correct:
https://notizen2019.netzjahre.com/2019/01/parkband-27/

What must I do that the WordPress Importer import theiframes, too?
Thanks in advance for your hints.
