combobox in the TabItem has an error

[ashe27]

The first parameter of BeginCombo cannot be left blank, otherwise it will not pop up correctly under the TabItem. I'm not sure if this is a bug.

if (ImGui::BeginTabItem("Test"))
{
    if (ImGui::BeginCombo("", "None"))
    {
        ImGui::EndCombo();
    }
    ImGui::EndTabItem();
}

It needs a non-empty label to compute the combo box's unique ID. The label can be hidden by prepending ## to it: ImGui::BeginCombo("##my_combo", ...).
