Fix completion pager not rendering after <a-semicolon> in prompt
Usually, the prompt resets "m_line_changed" after invoking the change handler: if (m_line_changed) { m_callback(m_line_editor.line(), PromptEvent::Change, context()); m_line_changed = false; } but with prompt '' '' -on-change %{ execute-keys <a-semicolon>vl } -shell-script-candidates %{ seq 100 } the change handler pushes a normal mode with "<a-semicolon>" and then hands back control to the event loop. Later when the normal mode is popped we run "Prompt::on_enabled()" but don't actually redraw the completion pager. Since the <a-semicolon> excursion by definition did not change our prompt state, we don't need to recompute completions, only render them. Do that. This helps commands that use preview the selected completion via a "prompt -on-change" handler.
