I wanted to configure some plugin in KMail, and was very confused that it has no configuration button. But then I realized that it is just not visible because there is horizontal scrollbar.

STEPS TO REPRODUCE
1. Set the KMail localisation to Russian language and restart Kmail.
2. Open Settings ("Настройка") -> Configure KMail ("Настроить KMail").
3. Open Plugins ("Модули") category.
4. Try to configure the New mail notification plugin.

OBSERVED RESULT
You cannot see its configuration button. See screenshot. You need to scroll right to be able to see it.

EXPECTED RESULT
The configuration button should always be visible.

SOFTWARE/OS VERSIONS
Operating System: Arch Linux 
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.109.0
Qt Version: 5.15.10
Graphics Platform: Wayland
KMail: 5.24.0 (23.08.0)

ADDITIONAL INFORMATION
You can try other languages too. With German for example, they are half-shown.
Also, I am interested, what is the purpose of that big text field on the right? It is _just_ for showing the one-liner plugin description? If so, why not get rid of it and add the plugin description under it when selecting one?
