layout_2020: Only count for content size for height of non-replaced inline elements

<!-- Please describe your changes on the following line: -->

Accorinding to https://drafts.csswg.org/css2/#inline-non-replaced, The vertical padding, border and margin of an inline, non-replaced box start at the top and bottom of the content area, and has nothing to do with the line-height. But only the line-height is used when calculating the height of the line box.
