[fix] Links in previews don't open on click

[wiese]

Describe the bug

Node.js version: v16.18.1

OS version: Fedora release 38 (Thirty Eight)

Description: Links in previews don't open on click. Is this an intentional security feature?

Actual behavior

Click on links in the email preview do not open after update from 3.0.10 to 3.0.17 (I assume due to ce6d443 – sandbox attribute).

Console error message, e.g. in chrome:

Blocked opening '<redacted>' in a new window because the request was made in a sandboxed frame whose 'allow-popups' permission is not set.

I can still work around this via "Open link in new tab" in the context menu (proving the link works in principle).

Expected behavior

Click on links in the email preview opens in new tab.

If no general safe solution can be found, maybe make the attribute value configurable by the (library) user.
