GtkComboBox list sometimes doesn't scroll when it's higher than screen
Steps to reproduce
Open LibreOffice Writer 6.2.0, go to Styles->Edit Style...->Font->Language.
Current behavior
List doesn't scroll neither with mouse wheel, nor with keyboard navigation keys, so that the part of the list beyond the edge of the screen can't be made visible, although it could be selected blindly with keys.
Expected outcome
It should be possible to scroll the list with mouse wheel and with keyboard navigation keys.
Version information
Manjaro Linux, gtk3 3.24.5 and 3.24.4. After downgrading to 3.24.3 ComboBox list scrolls as expected.
