Font list too long for screen, no scroll bars

When I select a font from the main editing window in LO Writer I get a list with scroll bars, which is vital as I have a lot of fonts installed.

However when I edit a style and want to select a font for bullets, there are no scroll bars and I can only see the first 35ish fonts in my list, so I cannot choose the font I need.

If I type the font name in, it is recognised from the list, but the character selection table doesn’t update so I can’t use that method.

What can I do? I assume this is a bug but I can’t find a reference to it by Googling.

I’ve taken a screenshot:

System details: Version: 6.1.4.2 Build ID: 1:6.1.4-0ubuntu0.18.10.1

Hello - I cannot confirm for my LibreOffice 6.1.5 and 6.2.1 installations on OpenSUSELeap 15.0 and using native LibreOffice installation packages (not those from my distribution) under KDE. I do have a scrollbar.

I just installed 6.2.1, no difference. I changed the application theme from Yaru to all the other options, no difference.
