The issue occurs under IE only and since Microsoft is discontinuing Internet Explorer on June 15, 2022, we decided to not fix it. You can see more at

Internet Explorer 11 desktop application ending support for certain operating systems.

Please encourage your users to use Google Chrome, Microsoft Edge Chromium, or Firefox instead of IE.
