Typing not working with ngx-translate

[JGhignatti]

Hey,

If I place an element like
<span typingAnimation [typeSpeed]="20" [startDelay]="0" [hideCursorOnComplete]="true">Typing Angular Animation</span>
it works, but when I use translate pipe from ngx-translate, the animation does not happen.
example:
<span typingAnimation [typeSpeed]="20" [startDelay]="0" [hideCursorOnComplete]="true">{{ 'TYPING_TITLE' | translate }}</span>

*Translate -> @ngx-translate/core version 9.1.1

Is it not supported?

Thanks
