Hello Thomas ColbertThomas,
Thank you for reaching out Microsoft Community. We really appreciate all the efforts that you did just to possibly resolve the issue.
In regards to your concern there is a different way to zoom in a page in the browser using a mouse , you can try to press and hold the CTRL key in the keyboard and using your middle finger to slide up to zoom in and slide down to zoom out.
If this answer your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
