Impress animations panel visualization issue

LibreOffice on KDE Neon, screen LCD 1024x768 (old).

The lower part of animations panel is only partially visible, so it’s impossible to select many animations or set the options.
The only workaround to select animation is to undock the panel, select and dock again (very annoying).

The only way to set the options is to use the right button menu on the animation.

There is a way to fix this issue?
