| > The baseline of an inline-block is the baseline of its last line box in the normal flow, |
| > unless it has either no in-flow line boxes or if its overflow property has a computed |
| > value other than visible, in which case the baseline is the bottom margin edge. |
| |
| Here we have 2 inline-blocks. The 1st one is has some zero-sized text, so its baseline is |
| at its top content edge. The 2nd one only has a preserved line break. |
| |
| From https://drafts.csswg.org/css2/#inline-formatting |
| > Line boxes that contain no text, no preserved white space, no inline elements with |
| > non-zero margins, padding, or borders, and no other in-flow content (such as images, |
| > inline blocks or inline tables), and do not end with a preserved newline must be |
| > treated as zero-height line boxes for the purposes of determining the positions of |
| > any elements inside of them, and must be treated as not existing for any other purpose. |
| |
| The forced line break prevents the line box from being phantom, so the baseline of the |
| 2nd inline-block is also at its top content edge. If it weren't for the forced line break, |
| the line would be phanthom and then the baseline would be at the bottom margin edge. |
| |
| Therefore, the inline-blocks should have their top content edges aligned. |
