Test case to reproduce the crash.

It seems grid layout logic does not consider the scrollbar size when computing the grid container's height. 
This may result in an incorrect sizing when using indefinite sized containers.

Besides, it's possible to make the layout logic to crash due to the fact that contentLogicalHeight can be a negative value if we render a case where content size is 0px.

Nit: Maybe you can use "css-intrinsic-dimensions/resources/width-keyword-classes.css".

Or simply something like "position: absolute" or "float: left" to force the shrink-to-fit.
