Presenter View gets out of sync with slide show when using animations

[maeries]

This issue is unique.

• [X] I have used the search tool and did not find an issue describing my bug.

Operating System

Linux (RPM package)

Version information

7.2.1.36

Expected Behavior

Slide show an presenter view preview should always show the same

Actual Behavior

Presenter view is one slide ahead

Reproduction Steps

1. Create presentation with two slides
2. On the first one place two objects, like two text boxes
3. give one of them an animation, e.g. "appear"
4. place something on second slide (technically not strictly necessary)
5. Start presentation with presenter view and press right arrow

On the first press nothing will happen on the slide show, but the element with the animation will appear on the preview. You have to press again for it to also appear on the slide show. But now the preview is already on the second slide.
