Solutions

1. Extend the context deadline proportional to content length
2. Retry typing with a fresh element lookup on failure
3. Ensure the editor is focused/visible before typing (click it first)
4. Check content size and strip problematic characters before publishing

Example fix

// before
if err := humanize.Type(ctx, contentElem, content); err != nil {
    return errors.Wrap(err, "输入正文失败")
}
// after
if err := contentElem.Click(input.Left); err != nil { return err }
if err := humanize.Type(ctx, contentElem, content); err != nil {
    return errors.Wrap(err, "输入正文失败")
}

if visible, err := contentElem.Visible(); err != nil || !visible {
    return errors.New("content editor not visible")
}

if err := humanize.Type(ctx, contentElem, content); err != nil {
    contentElem, ferr := getContentElement(page, contentElemTimeout)
    if ferr != nil { return ferr }
    if terr := humanize.Type(ctx, contentElem, content); terr != nil {
        return errors.Wrap(terr, "输入正文失败")
    }
}

When it happens

Trigger: humanize.Type(ctx, contentElem, content) errors: element detached after re-render, ctx cancelled/deadline exceeded while typing long content, or the editable region is not focusable at typing time.

Common situations: Very long body text exceeding the humanize typing budget within the context deadline; editor re-render triggered by the tag section; focus stolen by a popup; page became unresponsive during long video processing.
