|
|
// Chrome 83 and FF 78b6 agree with these values when the lone flex child is
|
|
// position:static instead of position:absolute. That is evidence that these
|
|
// values are all correct, because the position of a staticpos child is
|
|
// specified to be identical to the abspos position when there are no other
|
|
// children or specified offsets.
