Revert of Close the panel if show has been requested

Revert of Close the panel if show has been requested (patchset #1 id:1 of https://codereview.chromium.org/2097623003/ )

Reason for revert:
This patch does not entirely fix the issue since a panel can be opened by the panel manager without being requested.

Original issue's description:
> Close the panel if show has been requested
>
> When a panel is requested to show, it may not be visible yet and
> isShowing will return false. If two panels try to show simultaneously
> this can cause the incorrect panel to appear. This change keeps track
> of whether peek has been called so there can be a corresponding close
> call, regardless of panel visibility.
