Link to image does not show preview anymore

[MI-KY]

Steps to reproduce

Some time ago (unfortunately I can't say if this has to do with a specific version of tables) when I created a link to a image saved inside Nextcloud the table did not only show the link to the file but also a preview image (very little image).
Now, when you create a column with type "link" the table does not show any previews anymore.

The preview of the image does exist - this is also visible while you compile the fields:

But inside the table itself there is no preview - but there was one some versions ago:

Expected behavior

See a preview image of a link to a image

Only linktext is shown

I've looked into the code a bit.
Could the problem maybe arise because of

tables/src/shared/components/ncTable/partials/rowTypePartials/TextLinkForm.vue

Line 216 in 189050c

if (item.thumbnailUrl && !await this.isUrlReachable(item.thumbnailUrl)) {

checking the url of item.thumbnailUrl?
In fact when I directly call the ocs api the result for a request like <DOMAIN>/ocs/v1.php/search/providers/files/search?term=<Imagename> looks like this:

   <element>
    <thumbnailUrl><DOMAIN>/index.php/core/preview?x=32&amp;y=32&amp;fileId=123456</thumbnailUrl>
    <title>Imagename.jpg</title>
    <subline>path</subline>
    <resourceUrl><DOMAIN>/index.php/f/123456</resourceUrl>
    <icon>/index.php/apps/theming/img/core/filetypes/image.svg?v=af2ffedd</icon>
    <rounded></rounded>
    <attributes>
     <fileId>123456</fileId>
     <path>/path/Imagename.jpg</path>
    </attributes>
   </element>

With & in the url instead of &. Getting the url with & in it returns an empty response - the url with & returns the preview. So maybe the check for the url by isUrlReachable now always deletes the thumbnail?
