To repro:

1. On iOS, highlight a URL (eg, https://google.com) and copy it to the clipboard.

2. In Chrome, open the New Tab Page.

3. With the omnibox empty, tap the omnibox to see the autocomplete results.


Expected:

On iOS, when the omnibox is empty and the clipboard contains a URL, the only autocomplete result should be the clipboard URL.


Actual:
