I was able to reproduce this with your recipe.

I tried a few variations on your recipe to see if it always behaved the same way. One of the times I did it, I distinctly saw the right arrow step move the cursor over one character, followed by the briefest of pauses, and only then move it to the end of the line. This can be demonstrated by moving the cursor one character right with the arrow before typing anything, then using it after typing. (Search, click in results search box, right arrow, type a character, right arrow and see anomaly)
