gtktest "wrapping SpinButton" has glitchy behavior when holding buttons, or using keyboard arrows

[nyanpasu64]

gtktest has a "wrapping SpinButton". I'm testing on gtk-rs on Windows 10 with gtk via msvc vcpkg.

When I decrease the wrapping SpinButton past the end using keyboard below 10, it gets stuck at 90 until I increase the value to 10 or switch widgets. Above 90, it gets stuck at 10 until I decrease the value to 90 or switch widgets.

If I hold down the +- buttons, I can get the value past the 10..90 range, to 0 or 100.

I'm not familiar with gtk, but is binding the wrapping behavior to connect_input wrong? Should it be bound to connect_value_changed instead?
