XFCE large cursors - still small when over xterm

[Zenaan Harkness <zen@freedbms.net>]

I have chosen the black (with white border) cursor scheme, with 48
point cursor size. See:
Settings -> Mouse and Touchpad -> Cursor size

The cursor is mostly satisfactory, including over xfce4-terminal, except:

When the cursor is over an xterm, the vertical bar "text" cursor is
normal tiny (small) size, and not 48 point size (like when it's over
xfce4-terminal).

Anyone know how to fix this?

TIA
