| border: solid blue; |
| font-size: 1.5em; |
| white-space: pre-wrap; |
| } |
| .ref { |
| border-color: orange; |
| white-space: pre; |

| .red { background: #ffaaaa; } |
| .green { background: #aaffaa; } |
| .pink { background: #ffaaff; } |

| <p>Test passes if each pair of blue / orange boxes are identical (except for the color of their border). |

| <!-- not coloring the space between ا and ب in this particular case, |
| because per UAX9 L1 and css-text-3 4.1.2 point 4 bullet 2: |
| this space MUST be at the end of the line and hang, |
| but also the UA MAY collapse it's advance width. |
| Not giving it a color lets the test pass either way. |

| this space MUST hang, |

| So we know for sure it won't cause a line break, |
| but it may or may not be visible at the end of the line. |
