Multiline tooltip at right edge gets resized on click

[tzunghaor]

Bug description:

I have a button with a tooltip so far right, that the tooltip reaches the right edge of the window / position:relative container.
Clicking the button calls a method (irrelevant what it does, in the plunkr example it does nothing), and then unexpectedly the tooltip becomes narrower.
(I experienced something similar with popovers too.)

Link to minimally-working plunker that reproduces the issue:

Version of Angular, ng-bootstrap, and Bootstrap:

Angular: 5.0.2

ng-bootstrap: 1.0.0-beta.8

Bootstrap: 4.0.0-beta

Setting container="body" seems to solve this issue

@milasevicius - container="body" seems to solve it in the plunker for the centered button, but not for the button on the right.
