Fixed flaky test.

Fixed flaky test.

It appears to be an issue with the "textarea" not always getting focus
before the "commitText()" call is made.  A tiny delay to let everything
settle seems to fix the issue.

Let's use CriteriaHelper.pollForCriteria that checks for the focused element id.

The original details of the flaky test were gone and since there were no changes
to Chrome code, I submitted this in order to see if more reports came up.

The odd thing is that I un-checked the commit box but it still continued.

Don't know why I typed my own id, though...  Must have been muscle-memory or
type-without-thinking while remembering a drover merge.  Apologies.
