Zotero Beta viewer does not allow me to select text in certain PDFs


I'm currently using the Zotero beta (5.0.97-beta.63+035aac30f). I have a problem with certain PDF files created by ocrmypdf.

In Zotero I can search these files without problems (so Zotero does recognize the text) but cannot select and highlight text. In other viewers such as Okular or in Firefox they behave normally and I can select text, so it is not a problem with the files. Sometimes only certain pages in documents are affected but I have not found a pattern.

I have uploaded an example page, for which this problem appears here: https://heibox.uni-heidelberg.de/f/de6ec20a3af34a68ad9c/?dl=1. When I try to select all text on the page, it looks like this: https://imgur.com/a/9Afec0h

Thanks a lot!
