What happened?

I have instagram.com, threads.net and facebook.com all as pinned tabs in a workspace that has its own default container. The first time I open each of these tabs in a browsing session, I see a 'Secure Connection Failed' error page and the address bar says 'Not secure'. When I click 'Try again' they load correctly.

They continue to work for the rest of the browsing session (and if I switch between workspaces), but if I close Zen and re-open it, the same thing happens again.

There are other pinned tabs in the same workspace/container that work fine (e.g. bsky.app).

This does not happen in Firefox or other browsers.

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
