Description:
Scrolling with the mouse in the heading style chooser widget skips at least one row of available styles. If i use the keyboard arrows it select the next element, as it should be(but still jumps around confusingly). 

I also can't drag the scrollbar with the mouse at all. 

As a result i can't select any of the styles which come 
immediately after heading 1

There is also a tiny target directly above and below the scrollbar where you can click to scroll by 1 pixel, like an invisible arrow.

Launching Libreoffice with 

SAL_USE_VCLPLUGIN=gtk3 libreoffice 
or
SAL_USE_VCLPLUGIN=gtk4 libreoffice

the scrolling works just fine and is much smoother.

-I've attached a small video demo. In the video i first scroll with the mouse wheel, then i try to drag the scrollbar and then i use the keyboard arrows. 

Issue is also the same on x11.
