Awesome, can you give us the editor link please
could anyone reproduce this please? 
I am trying something new, but have always the problem that when adding width transition to a group the content inside this group is like flashing, because it looks as if the width is adjusted in the same step, but always at the current stage.
e.g. a text is first vertical before the full width is reached.
and then, depending on the progress of the transition, one more letter is always added at the end horizontally, which leads to a broken animation.
thanks!
