Reviewed by Sammy Gill.
315911@main incorrectly included preferredSize.isFitContent() in
GridLayoutUtils::preferredSizeDependsOnContainingBlockSize(), causing
grid items with fit-content to incorrectly contribute used minimum size
instead of min-content size when sizing tracks.
Note that our avoidance reasons are only allowing grids with auto and
fixed grid item widths to run
through
GFC.
