Works fine for me. I just tried clipping that page as markdown and it has the two images labelled "TenForums.com" with the explorer window and yellow highlighting.
I'm puzzled. I used Chrome and Edge and Edge in private mode, with no display of the explorer window. I do see the TenForums logo and many other icons, as well as a video image.
Out of curiosity, I opened one of the explorer window images in a new tab (Edge browser) and then used the web clipper.
Although I got the markdown text...

The graphic did not display in Joplin (including WYSIWYG). Again, if I right-click the browser image and "copy", the pasted image appears in Joplin.
Finally I opened Joplin on my freshly synced Android phone...and the explorer windows were missing.
