Hi. Thank you for an interesting solution. In style.css (child theme) I used only this part:
li#menu-item-390172:hover:after {
content: ‘Im here’;}
the rest is not needed – it works
I am sorry.
When I create a question in the administration and I want to insert an image, then it only opens up a few pages of pages with images stored in the media library and then it no longer loads.
But I’ve found that WP 5.9 does this whenever I want to select an image for a page or post. So some mistake with me. I’m going to look for what’s going on.
thank you for your helpfulness

Hello. Thank you for your response. The mistake was with me.
For some reason: thumbnails of the images were normally displayed in the media library, but did not appear in detail when one of them was selected. After deleting and re-uploading, everything was fixed. I just had to delete 200 images and upload them again 🙂
It also works with PHP 7.4
