Mouse click on other window causes node selection to be cancelled

[eminor1988]

I am not sure if it is the expected behavior for everyone or just in my usage scenarios.

By the design of my game engine, the user first selects some nodes in the graph, then the inspector window shows all properties of the selected nodes.

But when the user wants to click a button on the inspector window, suddenly the nodes are not selected anymore, and the inspector window does not show any properties of the nodes anymore (because the selection is canceled).

I added the IsWindowHovered() condition when selecting the node in "void BaseNode::update()", which fixes the problem:

// Orig:
if (!ImGui::IsKeyDown(ImGuiKey_LeftCtrl) && ImGui::IsMouseClicked(ImGuiMouseButton_Left) && ...)
    selected(false);

// My check:
if (ImGui::IsWindowHovered() && !ImGui::IsKeyDown(ImGuiKey_LeftCtrl) && ImGui::IsMouseClicked(ImGuiMouseButton_Left) && ...)
    selected(false);

And for the destroy(), I added the IsWindowFocused() condition

// Orig:
if (ImGui::IsKeyPressed(ImGuiKey_Delete) && !ImGui::IsAnyItemActive() && isSelected())
    destroy();

// My check:
if (IsWindowFocused() && ImGui::IsKeyPressed(ImGuiKey_Delete) && !ImGui::IsAnyItemActive() && isSelected())
    destroy();

But I am not sure if it is a bug or the expected behavior, so I am just reporting it here.
