After Clicking 'read more' link on a cell and moving to next slide without collapsing it. slider has whitespace below equivalent to height any previously expanded cells.

When you click the read more link on a cell, the height of the slider adapts to the height of the cell.  The issue is that if a user moves to the next slide without collapsing the cell back to its reduced size, then there can be a lot of whitespace on the next slide because the slider is still accommodating that expanded cell even though it's not being displayed anymore.  In addition to the whitespace, it also makes the nav buttons sit inconveniently far down below the slider, as it looks like they are set to be centred with the height of the slider.  Please see attached example.

Can you please make the slider reset any expanded cells once they're no longer being displayed?
