Flickering in breadcrumb displaying

[1nfinite]

Not sure whether i miss out something during configuration. But it seems that the breadcrumb display do flicker when navigation of same hierarchy. But ultimately, the breadcrumb display the correct label at the end.

For example,
Switching from Register to Login page and vice versa.
Switch from Register to Login:
Home/Register -> Home/Login/Register (flicker 1 second) -> Home/Login

Switch from Login to Register:
Home/Login -> Home/Register/Login (flicker 1 second) -> Home/Register

When keep switching from Register to Login and vice versa quickly, it will keep append in follow way:
Home/Register/Login/Register/Login but after pausing for 1 second, it will show the final correct breadcrumb which is Home/Register or Home/Login depending on last click.

Confirm issue with nganimate. Remove nganimate or do css tweaking can resolve the issue.
