Subject: [PATCH] Fix toggling of MenuItem and Selectable with build_with_ref

Selectable or MenuItem should be toggled on click when called with
build_with_ref.

This is the behavior that is done in ImGui when
`bool ImGui::MenuItem(const char* label, const char* shortcut, bool*p_selected, bool enabled)` is called.
