Where is the problem occurring?

I encountered the problem while using the application (Frontend)

What browsers are you seeing the problem on?

Safari

Current behavior

PDFs only load once, clicking a second time on the attachment results in an empty grey inline viewer. After reload ("⌘" + "r") they will be shown once again
PDFs in a resized Browser ("⌘" + "+" or "-") are not shown at all

Desired behavior

No response

Steps to reproduce

Create a new card. Upload any kind of PDF. Click on the uploaded PDF. It will be opened once. A second time it will not open until you force a browser's refresh. Or, the other part of the bug, resize Safari, click on the PDF, even the inline viewer will not be displayed (only the name of the file in white letters will be shown).

Other information

Yep, I was able to reproduce it and already looking into a fix.
