Thanks for the question regarding the zoom panel.
I’m not able to see an attachment, would you be able to reply with the screenshot so I can look more into the issue?
Additionally, if you are able to provide any more information about confirming the issue on the demo site + PDFTron that would be helpful in terms of letting us reproduce the problem. Specifically, if you can link to a demo page where you experienced the issue and some reproduction steps (or a screenshot showing the issue would work as well).
