Bug 184217 – line breaking should be possible between alphanumeric and fullwidth opening punctuation

• Component: Text
• Status: RESOLVED CONFIGURATION CHANGED

Test HTML+CSS at: http://jsbin.com/hobiko/edit?html,css,output
or:
```
<style>
p {
  width: 10em;
  background: yellow;
}
</style>
<p>あいうえおかきくけa「さしすせそ」</p>
<p>あいうえおかきくけ1「さしすせそ」</p>
```

What is the expected behavior?
Line breaking should occur as follows:

```
あいうえおかきくけa
「さしすせそ」

あいうえおかきくけ1
「さしすせそ」
```

What went wrong?
Line breaking occurs as follows:
```
あいうえおかきくけ
a「さしすせそ」

あいうえおかきくけ
1「さしすせそ」
```

It seems that line breaking is mistakenly prohibited between non-cjk letter or number and fullwidth opening punctuation such as "「".

This seems to be fixed. Murakami-san, please re-open or message me if there still remains any problem.

P.S. Thanks for including the testcase inline, the JSBin is not loading for me, but I could make the testcase with this information. :)

I reported this bug a long time ago and then forgot about it. I have confirmed that it is now fixed.
