Plugin loses effect with vertical split planes

[RichardCoppin]

As soon as I add a frame below the sliding panes I lose the sliding panes effect, the file header gets moved to the top.

If I remove the bottom pane, then I can recover the sliding panes effect, by removing all but one note, and then as I add them back they all have the sliding panes.

I can add whatever frame I like as an additional sliding pane but I cannot add any pane below the sliding panes.

Here are the sliding panes working as expected:

When I try to add a frame below, the sliding pane effect stops.

Fixed upon integration with Obsidian v1.0, but now the new vertical pane needs to be manually changed to sliding panes, even if it was the default.
