We are currently developing a PowerPoint content add-in and have encountered an unusual behavior during presentation mode. When a slide containing the add-in is displayed for the first time, it initially appears at a smaller size before resizing to its intended dimensions. This resizing process can be quite distracting for users, and we are seeking a solution to enhance the loading experience.
Has anyone else experienced this issue, or could you offer any suggestions on how to address it?
To illustrate the problem, I have created a recording using a publicly available add-in that closely resembles the one we are developing.

Based on our investigation, it appears that the add-in is initially rendered at the same size as it was displayed in the editor view. Subsequently, PowerPoint adjusts it to the correct dimensions. (This resizing can also trigger some layout changes within the add-in, which we have managed to resolve.)
