In the old logic, the table's content inline size is stored in the `min`
variable, and passed into `AddIntrinsicSizeOffset()` to account for margin,
border, and padding.
We don't seem to have test coverage for this behavior, so I added some WPTs in
the next part.
This patch shouldn't change behavior.
