split-windows not tiling

[dasunsrule32]

When opening a new-session and splitting more than 6 windows, tiling doesn't seem to work properly. It just drops all the split-windows into a horizontal split and performs no tiling. It works fine with 5 or less.

My working config with 5:

new-session -n name ssh prod01;
split-window ssh prod02;
split-window ssh prod03;
split-window ssh prod04;
split-window ssh prod-server;
select-layout tiled;
select-pane -t 0

My config that works, but doesn't tile properly:

new-session -n name ssh prod01;
split-window ssh prod02;
split-window ssh prod03;
split-window ssh prod04;
split-window ssh prod05;
split-window ssh prod06;
split-window ssh prod07;
split-window ssh prod08;
split-window ssh prod09;
select-layout tiled;
select-pane -t 0

OS: RH 7.9
Shell: GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)
byobu: byobu version 5.133 tmux 2.9a

Let me know if you need anything else. This is the archive straight from launchpad as well. Thank you. :)

An Ubuntu task was created. Does this also affect byobu in Ubuntu?
If so, please advise which release(s) is/are affected.
