<!-- 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,
