Using system monospace font affects context menus

[Akbarkhon Variskhanov]

1) Xubuntu 20.04.3 LTS
2) mousepad (0.4.2-1)
3) The "Use system monospace font" preference should only affect the text being typed
4) It also changes the font for context menus

Screenshot is attached.

The reason is that GtkMenu being spawned inside GtkTextView and the font-family property is inherited from parent. If GtkTextView is set to monospace font, GtkMenu also inherits that font.

The fix would be setting its value to initial. The following Gtk code does that:

.context-menu {
 font: initial;
}

I don't know how it would be done programmatically, though:

This no longer seems to be an issue with Mousepad 0.5.10 in Xubuntu 22.10. Please reopen if you see otherwise.

I can confirm that it is indeed fixed with Mousepad 0.5.10.

Thank you.
