[jlreq] Line start and end prohibition rule not fully supported (#274)

himorin has just created a new issue for https://github.com/w3c/jlreq:

== Line start and end prohibition rule not fully supported ==
Some characters are listed in line start and end prohibition rule, and some levels exist for set of prohibited characters. 


<b class="subhead">Specs:</b>
[css-text-3](https://drafts.csswg.org/css-text-3/#line-break-property) defines `line-break` property with three levels `strict`, `normal`, and `loose` to switch among sets of prohibited characters.

<b class="subhead">Tests & results:</b>
<i>web platform test</i>, [lists test for three levels](https://wpt.fyi/results/css/css-text/line-break?label=experimental&label=master&aligned)

<span class="partial">Gecko</span>, <span class="partial">Chromium</span>, and <span class="partial">Webkit</span> partially support three levels.


<b class="subhead">Browser bug reports:</b>
[Chromium](https://crbug.com/1091631) • [Webkit](https://bugs.webkit.org/show_bug.cgi?id=195275), [Webkit](https://bugs.webkit.org/show_bug.cgi?id=183258)


<b class="subhead">Priority:</b>
The impact of this is probably more important for advanced layout.
