When using Safari, the "Content browser" pop-up (tab: Browse) does not display anything.
Steps to reproduce:
1. Login as admin (using Safari)
2. Select "Content" -> "Content structure"
3. Select "Content browse"
1. "Content browser" pop-up appears. The "Browse" tab does not display any content (screen from Safari )
1. "Content browser" pop-up appears, the "Browse" tab allows to choose from available content (screen from Chrome )
I've verified that this pop-up displays content correctly on Firefox, Chrome and Edge (only Safari is affected). On Safari there are multiple ways to reproduce this issue, e.g. clicking "Embed" button when editing a description of a new Content item.
