Original change's description:
> [omnibox] [rich-autocompletion] Unelide omnibox before setting focus.
> 
> With the 1-line UI, rich autocompletion adds a label adjacent to the
> omnibox and then resizes the two as the autocompletion length changes.
> 
> On location bar focus, the omnibox is unelided; e.g. google.com is
> unelided to https://www.google.com.
> 
> Before this CL, unelision occurs *after* the location bar is given focus
> and its layout computed.
> 
> With this CL, unelision occurs *before* the location bar is given focus
> so that it can reserve sufficient width for the unelided URL when
> updating its layout.
>
