max-height animation after grid reflow

[eslotwinski]

I'm looking for a way to "reflow" a grid before it's actually going to reflow. What i mean is, i'd like to add an animation which cause a change in height of an element and wait with animation to this element, before the grid(reflow) will make a space for my element.

@s-yadav do you have any sugestion how to make this and sync the animation?
