Context menu for first element in a horizontal_wrapping layout doesn't open

Self contained example with eframe:
```Rust
use eframe::{egui, NativeOptions};

struct App {}

impl eframe::App for App {
fn update(&mut self, ctx: &eframe::egui::Context, _frame: &mut eframe::Frame) {
egui::CentralPanel::default().show(ctx, |ui| {
ui.horizontal_wrapped(|ui| {
for _ in 0..100 {
ui.link("Right click me").context_menu(|ui| {
if ui.button("Hello world!").clicked() {
ui.close_menu();
}
});
}
});
});
}
}

fn main() {
eframe::run_native(
"Test app",
NativeOptions::default(),
Box::new(|_| Box::new(App {})),
).unwrap();
}
```

The context menu doesn't open for these links:

eframe 0.21.3
egui 0.21.0

#2962 might be related.

Run the self-contained eframe example and compare the first link with later links in the horizontal_wrapped layout. Start by tracing horizontal_wrapped and context_menu behavior, and check the related #2962 issue. Done means the context menu opens for the first element and the behavior is covered by a regression test.
