Drop downs in LibreOffice are cut off when using a Kvantum theme

I wonder if you could help me to fix this issue, or at least to direct me where to report it:

  1. all drop downs in LibreOffice apps are cut of from the left

    WM Theme: WhiteSur-Sharp
    Theme: WhiteSurDark [Plasma]

I’ve found the culprit and moved the issue over here:
