 I uploaded a test placeholder image called "300x250.png" and it allowed me
 but it wasn't displaying a preview in the media library, or working when I
 tried to select it as a property of a page builder element.

 Took me a few minutes to realise what was happening but internally
 WordPress uses a filename suffix in the format of something like 100x100
 and naming the image 300x250 was obviously confusing things.

 Renamed the file to teamplaceholder.png and it worked fine.

 I guess it needs some kind of invalid filename filter incorporating to
 either block it from being uploaded or to silently rename it to a
 compatible name?
