Hitting Tab key when focus is on Next button in Find bar should not dismiss it.

[RaymondLim]

1. Open a page with some text that you can do Find Next or Find Prev.
2. Hit Ctrl/Cmd+F to bring up the Find bar.
3. Type some text that has multiple instances in the current document.
4. Hit Tab keys three times.

Result: Find bar closes.
Expected: Tab key should cycle through all elements in the Find bar. That is, if the focus is on the last element, Tab should set focus to the first one. And if the focus is in the search field and Shift-Tab keys are pressed, then the focus should go to the last element in the Find bar.

Reviewed. @redmunds - please work with @rajeshsegu to see if he can help with this.

Before the prev and next buttons were added, this was the behavior when hitting tab in Find text field. I assumed this was by design, so I just submitted pull request #5848 for #5766 that restores this behavior to the text field.

Since the Find, Replace, and Find in Files dialogs will be totally rewritten soon, I don't think this is a Medium Priority, and I don't think we should spend time on this.

This is also fixed (actually made obsolete) by pull request #5848.

Closing since we no longer can tab to those buttons.
