Symptoms
When clicking an image attachment in RoundCube, the full image is not fit to the window. Also when attempting to zoom in or out these buttons do not function.
Description
You can still scroll within the window that appears, however, there is no way to see the full image at once.
We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-45847. Follow this article to receive an email notification when a solution is published in the product.
