When reducing terminal size, bar will not remain in the same line in each rendering. Is it a bug?

[Andrew-M-C]

• Device: MacBook Pro 13-inch, 2020
• Terminal: build-in Terminal application
• Description:
  • After the width of terminal got thinner, the previous bar remain above (which is acceptable).
  • But the new bar kept starting new lines and re-render each progress, which may not be acceptable.
  • Please refer to attached screen capture file.

	for i := 0; i < 100; i++ {
		bar.Set(i)
		time.Sleep(50 * time.Millisecond)
	}

	bar.Clear()
	w, h, err := term.GetSize(int(os.Stdout.Fd()))
	So(err, ShouldBeNil)
	t.Logf("Done, terminal size: %d x %d", w, h)
