Current behavior

I have a container with scrolling enable. Into the container I have several inputs setting like the documetation recomend for this case:

<div class="scrolling-view">
    ...
    <div #container style="display:inline-block;position:relative">
        <input type="text" pInputText pTooltip="Enter your username" placeholder="Right" [appendTo]="container">
    </div>
    ...
</div>

The tooltip appears in a incorrect position, far from the input.

Expected behavior

The tooltip must appears in the postition indicated next to the input.

In fact, I don't understand how this can work for someone because looking at the code, I have seen that to positionate it you use the method getBoundingClientRect which always returns the bound regarding to viewport, not the relative position where the tooltip was appended.

Please tell us about your environment:

• Angular version: 5.0.0

• PrimeNG version: 4.3.0

• Browser: [all]

• Language: [TypeScript 2.4.2]

• Node (for AoT issues): node --version =

This is a problem for me, as well. Using the provided guidance for 'appendTo', the tooltip is incorrectly positioned on the screen.

I have the same problem with a tooltip inside a fixed header on the top page.
