What happened?

Using 1.7.4b zen browser in windows 11.
In Microsoft Outlook as a tab, pinned tab, or essential pin across workspaces, when clicking "New Mail" or "Reply" to an email the new Draft section will start to load but as the Signature is displayed, the page will automatically refresh.
If I go into the drafts folder an attempt to load a draft to edit, then the page will get stuck in a refresh loop.
The browser remains stable and the tab can be exited.
A full computer restart does not solve this problem, it is consistently repeatable.

Fans ramp up and there is a small CPU spike visible in Task Manager when a reload happens, then performance returns to normal.
The issue does not occur on Mozilla Firefox.

Reproducible?

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

Same issue for me with v1.7.6b, but opening a draft only leads to a refresh and not a refresh loop.
