Hi, QingYang Liu
Welcome to the Microsoft community.
We were able to reproduce your issue. We tested using the Canary version and still encountered the same problem. Since the feature in Edge is currently in beta, issues are not uncommon. Given that we can all replicate the problem, I believe it is a compatibility issue between Edge and the extension causing the issue. As this is a functionality-related problem, please click on the Edge menu button, scroll through to "More Features," and report the issue to the Edge developers. I also suggest that you report the issue to the extension developers.
Best regards
