Cell content is not recentered after outputs are displayed

[jpdehollain]

Description

Before running a code cell in slideshow mode, the content of all the cells in that slide is centered vertically on the screen. After running the cell, if the cell displays some output (e.g., with print or if plotting a figure), the slide content is not recentered vertically, potentially causing the outputs to be cut-off from the screen.

Reproduce

1. Create a notebook that includes a code cell that generates some output, such as a plot
2. View the notebook in slideshow mode and run the cell

Expected behavior

After displaying the output, the content shown on the screen should be re-centered vertically

I found an ok workaround. After the figure is displayed, click on it and all the content on the slide gets re-centered

I have the same issue.

@jpdehollain What browser are you using? It doesn't work for me on Firefox.

Is there any way to "reserve" the space? Or to specify that a specific slide should be aligned on top instead of centered?

@kir0ul I have tried with Edge and Firefox and both work for me
