Hover state object appears behind base layer object
I have several screenshot images side-by-side on a slide (to mimic the ribbon in MS Excel). Each screenshot image has a Hover state where the image is enlarged to make it easily visible. However, when I preview the slide and hover my mouse over the screenshot, the enlarged hover image appears behind the other screenshots on the base layer that are beside it. How do I ensure that the Hover state of my object displayed above the base layer objects? Is there a workaround?
Any help is appreciated. Thanks!
