What steps will reproduce the problem?
(1) Enter this text into a text field:
abc ‭ا def
NOTE: This contains a U+202D LEFT-TO-RIGHT OVERRIDE character. Specifically, this string is:
abc \u202d\u0627 def
(2) Place cursor in the "abc" part.
(3) Hold right arrow.

What is the expected output?
The cursor advances through the string to the right-most character.

What do you see instead?
The cursor cycles through the "abc" repeatedly forever (it never gets through the U+202D).

Only happens in web contents textfields (i.e., not Omnibox).
