Problems with inline boxes and row boxes

recently, I have been reading articles about the layout of elements in the line, and many of them will quote the above picture

this picture refers to the detailed explanation of each part of the css line box
, but some articles say that the height of the
row box is made up of the bottom of the lowest line inner box to the top of the highest line inner box.
I agree with
if according to this view, this picture should refer to the model of the line frame, not the model of the line box.
line-height should also affect the line box by affecting the height of the line box. Height
I don"t know if my idea is correct. But if my idea is correct, this row-frame model should be wrong
, but this picture is so popular, can anyone answer it

the height of the row box is made up of the lowest end of the inline box to the top of the highest inline box

line-height should also affect the height of the row box by affecting the height of the box inside the row

that's right, but it doesn't mean the picture is wrong. It's not contradictory. You can't see how many line boxes there are in the picture alone, but you can be sure that there is one line box.
