[patrickelectric]

Describe the bug

To Reproduce Steps to reproduce the behavior:

1. Get the example

2. Add the following code:

   egui::SidePanel::right("egui_demo_panel")
   .resizable(false)
   .default_width(150.0)
   .show(ctx, |ui| {
     ui.vertical_centered(|ui| {
         ui.heading("Services");
     });
   
     egui::ScrollArea::vertical().show(ui, |ui| {
         ui.with_layout(egui::Layout::top_down_justified(egui::Align::LEFT), |ui| {
             if ui.button("Potato").clicked() {
                 self.tree.add_window(vec!["Potato".to_owned()]);
             }
             if ui.button("Organize windows").clicked() {
                 ui.ctx().memory_mut(|mem| mem.reset_areas());
             }
         });
     });
   
     ui.separator();
   });

3. Run the code, click in the Potato button on the right side

Expected behavior This should not happens, using egui 0.27

Hey, this is not a bug in the library. Each tab must have a unique ID which by default is derived from the tab title, so if you have two tabs with the same title, naturally there will be an ID conflict. You can override that behaviour by implementing TabViewer::id.

Let me know if that fixes your issue.
