Mouse-wheel scroll behaviour over child windows

[Tom-Evers]

Version/Branch of Dear ImGui:

Version: 1.71
Branch: docking

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_win32.cpp + imgui_impl_dx11.cpp
Operating System: Windows 10

My Issue/Question:
When scrolling a tall list that contains another scrollable field, that subfield 'captures' the mousewheel scroll action.
This should not be default behaviour: when the mouse does not move, the mousewheel should keep affecting the field that the scroll action originated in.

Screenshots/Video

Standalone, minimal, complete and verifiable example:
Build and run the docking branch.

This is an interesting idea, I admit I hadn't thought of doing it this way (locking the target scrolling window until moving the mouse again). I'll give it a try when possible. I think OS X behaves the same way as we currently do. Also see #1245

(Apologies, I have posted a message stating this was fixed but was thinking of a totally different issue. Deleted the wrong message and re-opened this.)

Hello @Tom-Evers
I have now implemented this feature and pushed it into master. It will be merged in docking shortly (you may merge it ahead if you want).
