input[type="search"]:focus {
  outline-width: 6px;
}

fixes the problem.  Is this a correct fix?

I'm not sure what is the root cause.
I investigated how RenderTextControlSIngleLine::layout() and paint() were called.
When a user types a key, the followings are called:

r90088:
layout(), layout(), PaintPhaseBlockBackgound, PaintPhaseChildBlockBackgrounds, PaintPhaseFloat, PaintPhaseForeground, then PaintPhaseOutline.

r90089:
layout(), PaintPhaseBlockBackgound, PaintPhaseChildBlockBackgrounds, PaintPhaseFloat, PaintPhaseForeground, then PaintPhaseOutline.

It seems that there are no differences of the number of outline paintings.
