Incorrect sizing and icon in a panel of type "Deskbar" with multiple rows

I have noticed incorrect sizing and cut-off icon of the plugin when used with a panel specified as "Deskbar" (vertical) with multple rows.

My panel size is set up for 2 rows, 32 pixels each, type "Deskbar". The mount plugin, when added, takes double vertical space, but single horizondal space, compared to other apps and system tray entries. Its icon is small size, sort of matching the other plugins, but actually presents 1/4 of the original icon.

Example:

When changed to a very small-size icon (like half of the size of my row - 16 pixels for my example), it displays is right(ish), but still takes double space vertically and normal space horizontally.

Example:

It works fine, but looks not so great and makes a mess among other neatly arranged plugins.

I'm using Manjaro with Xfce 4.18, GTK 3.24.43, kernel 6.10.13-3.

If you need any more information, I'm happy to help.
