I appreciate the response!
I could assign a min-height. What I'm saying is I don't think that really addresses the underlying problem.
What happens is the div within the container programmatically gets assigned a new height.
The md-card that wraps it does not automatically resize along with it.
It is true that assigning min-height or an explicit height might make the dashboard container initialize with more space (to the tune of whatever height or min-height is assigned), but it still won't be accurate when it gets resized.
Put simply, when dynamic resize happens, NodeRED will still think the height is whatever it initialized to.
What I'm trying to do is programmatically notify Dashboard of the new height or force a refresh, so that all elements in the group get updated with the proper coordinates (as each has explicit x/y coords assigned in style by dashboard)
