--- Comment #1 from elidoset at gmail.com ---
I've done a first investigation myself on the question, and I found the problem to be here : https://github.com/WebKit/WebKit/blob/ef93c1b412c09e10975907c8fd683269eb36a413/Source/WebKit/Shared/gtk/NativeWebWheelEventGtk.cpp#LL41C13-L41C13

The modifier events that could have been extracted from the GtkEventScroll are not transmitted to the constructor of WebEvent. This is handled better for key presses (https://github.com/WebKit/WebKit/blob/ef93c1b412c09e10975907c8fd683269eb36a413/Source/WebKit/Shared/gtk/WebEventFactory.cpp#L259), where a factory function parses the GtkEventScroll.state property and transmits the modifier keys using the modifiersForEvent(const GdkEvent*) function. 

This is my first time delving into the Webkit codebase and I'm not a professional programmer so I don't really want to make the change myself, but I can try if nobody's up for it...
