How to scroll to cursor in TextEdit, without using ScrollArea?

[TetraTheta]

In C# WinForm, I can scroll to the end of the TextBox with this simple code.

textBox1.SelectionStart = textBox1.Text.Length;
textBox1.ScrollToCaret();

But I couldn't find out any similar code that is usable in egui.

By default, TextEdit sets its cursor to the end of the text, but this doesn't move its view, so only front part of the TextEdit is shown.

// ...
let mut from: String = remove_unc(self.target.clone());
let mut to: String = remove_unc(self.output.clone());
ui.horizontal(|ui| {
  ui.label("From: ");
  ui.add(TextEdit::singleline(&mut from).desired_width(f32::INFINITY).cursor_at_end(true));
});
ui.horizontal(|ui| {
  ui.label("To:   ");
  ui.add(TextEdit::singleline(&mut to).desired_width(f32::INFINITY).cursor_at_end(true));
});
// I know that `.cursor_at_end(true)` is not necessary :(
// ...

I don't know why only the cursor of first TextEdit sticks to end of the text while the cursor of the second TextEdit doesn't.
But anyway, both are not what I want.

Using ScrollArea is not what I want, because by using it, user is basically scrolling the whole TextEdit, rather than the content/text of TextEdit.

I couldn't find out proper method for forcing the cursor to be appear at the screen, just like how I did in WinForm.

How can I do it?

I just found that TextEditState.singleline_offset might be used for setting which part of the text are shown, but it is public within the crate itself.

pub struct TextEditState {
    /// Controls the text selection.
    pub cursor: TextCursorState,

    /// Wrapped in Arc for cheaper clones.
    #[cfg_attr(feature = "serde", serde(skip))]
    pub(crate) undoer: Arc<Mutex<TextEditUndoer>>,

    // If IME candidate window is shown on this text edit.
    #[cfg_attr(feature = "serde", serde(skip))]
    pub(crate) ime_enabled: bool,

    // cursor range for IME candidate.
    #[cfg_attr(feature = "serde", serde(skip))]
    pub(crate) ime_cursor_range: CursorRange,

    // Visual offset when editing singleline text bigger than the width.
    #[cfg_attr(feature = "serde", serde(skip))]
    pub(crate) singleline_offset: f32,

    /// When did the user last press a key or click on the `TextEdit`.
    /// Used to pause the cursor animation when typing.
    #[cfg_attr(feature = "serde", serde(skip))]
    pub(crate) last_interaction_time: f64,
}

That is correct. I think this is a bug.
