This is how Konsole incorrectly renders Byobu's TUI

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

***
Recently upgraded to Konsole v23.08.0 on Arch, which broke how the console is
rendered when using Byobu with tmux.

Before the upgrade, using Byobu with tmux and Konsole was fine. This error
occurred on two different machines after updating Konsole.  Other terminal
emulators on the systems all render Byobu's TUI correctly.


STEPS TO REPRODUCE
1. Install Konsole v23.08.0
2. Install Byobu
3. Run `byobu`, select the tmux backend (note: I haven't tried with the screen
backend)
4. The default Byobu status bar should have some text widgets in the bottom
right corner. If not, hit F9 and enable the date and time widgets and hit F5 to
refresh the TUI.

OBSERVED RESULT
Konsole fails to render the Byobu TUI correctly. To me, it looks like Konsole
will render the Byobu status bar with a trailing newline where no newline
should exist. 

EXPECTED RESULT
Konsole should render Byobu in the same way as other terminal emulators on the
system do, and the same way that Konsole versions prior to v23.08.0 did.

SOFTWARE/OS VERSIONS
Operating System: Arch Linux 
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.109.0
Qt Version: 5.15.10
Kernel Version: 6.4.12
Graphics Platform: Wayland

ADDITIONAL INFORMATION
Here is how Byobu should be correctly rendered:
