Oh, so I had taken it completely wrong. OK, just to be 100% sure, you 
mean that it does not apply for example to the following example:

<div style="display: grid; width: min-content;"></div>

I was assuming that the above was a grid container sized under 
min-content constraint, but from your answer this is just a grid with an 
indefinite width so the maximize tracks step will grow all the tracks to 
their growth limits. Is that correct?
