[GNC] GnuCash transfer column pull down not working in MATE

[ToddAndMargo]

Hi All,

Fedora 34
mate-desktop-1.26.0-1.fc34.x86_64
Xfce 4.16
gnucash-4.6-2.fc34.x86_64

GnuCash transfer column pull down not working in MATE:
    https://github.com/mate-desktop/mate-desktop/issues/484
    https://bugzilla.redhat.com/show_bug.cgi?id=2010544

The drop down arrow at the far right of GnuCash's transfer column does 
not put of a list of transfer account. The problem does not reproduce in 
Xfce (I have both desktops installed)

Anyone have a work around for this.  Otherwise this is
a deal killer for MATE-Desktop

Many thanks,
-T
