Previews does't work in 5.7.10 light J4

Hi,

Thanks for contacting us here about this extension.

I'm testing dropeditor 2.5.16 / dropfiles 5.7.10 light in a j3.10 and in a J4 local installation. I see that in the same light component the preview of the Pdf or word or any other format woks on a J 3.10 but not in J4. Is it a bug?

Our previewer is based on Google viewer, and it may cause an issue sometimes with a few file types.
However, we've planned to implement our previewer in the 6.1 version (currently 6.0.2)


Thanks a lot!
Best Regards,
