If I click to open a URL from a card on the Trello Mac desktop app, it opens in another Trello window. Is it possible to get it to open in Safari?

Additional information after further testing
I have done some further testing:
- Directly type link into description field (underlined in green) -> link opens in Safari.
- Use iOS share sheet to share URL to new Trello card (comes in as an attachment) -> opens in a separate Trello window.
- Copy URL from attachment link and paste into description -> opens in a separate Trello window.

This behaviour is the same across 2 Macs. Clicking the attachment link in Trello on iOS opens the link in Safari.
