tooltip increases the length of the page

[StennikovDmitriy]

I have found that when the tooltip disappears for a moment the page length is increased by the tooltip element height.
Tooltip configured with appendToBody: true

$uibTooltipProvider.options({
            placement: 'top',
            animation: false,
            popupDelay: 0,
            appendToBody: true
        });

Markup is trivial

<a href="#" class="btn blue" uib-tooltip="Edit">
    <i class="fa fa-edit"></i>
</a>

Tooltip element at this moment (when it disappears) looks like:

Normally, the the element has a style: style="visibility: visible; display: block; top: 513px; left: 1688.25px;"
visibility:hidden in fact, it does not hide the the element and it appears at the end of the page. The page length increases, for a moment appears a scroll bar.

I think should be display:none instead of visibility:hidden or just don't remove top & left position.

Bootstrap: 3.3.4
angular: 1.3.16

The obvious hotfix:

.tooltip { top: 0; }

The tooltip service is used for both popovers and tooltips which have different css implementations. Using display: none causes issues with measuring the popover height and width for top and left calculations. Recent PRs #4621 and #4623 attempt to put this issue to rest once and for all.
