Further information

Reproduction steps:

1. zellij setup --dump-layout default > ~/.config/zellij/layouts/default.kdl
2. zellij setup --dump-swap-layout default > ~/.config/zellij/layouts/default.swap.kdl
3. vim ~/.config/zellij/layouts/default.swap.kdl
4. Edit the swap_tiled_layout named stacked that comes by default to

swap_tiled_layout name="stacked" {
    ui {
        pane stacked=true {
	    children
        }
    }
}

5. Save :wq
6. Start zellij
7. Create 2 new panes by ALT + N (3 total panes)
8. Swap to the STACKED swap layout by pressing ALT + ]
9. See all the panes are stacked below each other
10. Try to create a new pane by pressing ALT + N, but nothing happens. Trying CTRL+P -> d to split down shows CANNOT SPLIT and also CTRL+P -> r to split to the right shows CANNOT SPLIT

Workaround:
The workaround seems to be switch back to the HORIZONTAL or VERTICAL swap layout, then create the new pane, and then switch back to the STACKED swap layout
