feh_event_handle_ConfigureNotify ignores window geometry change when called too early

[Flexlolo]

My goal is to make feh behave as if its in fullscreen while being effectively tiled.
I created a custom rule on BSPWM "bspc rule -a feh state=tiled" that forces feh to be tiled.
Launching feh with -F does indeed make it pseudo-fullscreen and tiled, but the image is not resized accordingly.
According to the log feh_event_handle_ConfigureNotify is being called but the following if statement fails:

if ((w->w != ev->xconfigure.width) || (w->h != ev->xconfigure.height))

Without looking too much at the winwidget code, I assume its related to window mapping.
Would it be possible to address this by queuing the event or changing if statement?
Below is full log and screenshot of an example.
In the log you could see second event handled properly once the window is mapped.
