Describe the bug

When the mouse cursor is hidden, the menu entries should not be highlighted like when a mouse pointer is hovering above them.

N/A

Steps to reproduce

1. Enable HideKB in Options -> Interface -> Mouse control options -> Hide mouse cursor
2. Position the mouse cursor over your character
3. In game, press Enter
4. The menu entry in the middle of the screen is highlighted but there is no mouse cursor visible. See screenshot "5 Inventory ...".
5. Move the mouse. Now the menu entry is highlighted under a visible mouse cursor

Step 4. above should not happen. That is, if the mouse is hidden the uilist entry should not be highlighted.

Additional context

Trying to fix on my own in ui.cpp void uilist_impl::draw_controls(). However, the logic for highlighting is embed into ImGui and quite complex to follow. Hope the ImGui experts can have a look, thanks.

HideKB option only hides mouse cursor in our SDL curse implementation. In imgui there ARE ImGui_ImplSDL2_UpdateMouseCursor with SDL_ShowCursor calls.

To hide mouse cursor either ImGuiConfigFlags_NoMouseCursorChange should be set or MouseDrawCursor should be set to false.

You can try to go with the following in cataimgui.cpp:

    ImGui::GetIO().ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange;

Tried but no luck. The logic to decide when to highlight is inside ImGui::ButtonBehavior, being bool hovered the most candidate. ImGui does not ignore highlighting also when I set ImGuiMouseCursor_None.
