01The signal

The report, exactly as it was filed.

Nothing paraphrased or cleaned up. The mess is the thing under test.

find() convert `xlink:href` to `href`


`cheerio@^1.0.0-rc.2` automatically converts `xlink:href` to `href` when using `find()`.

```js
cheerio.load('')('<span><svg ><use xlink:href="#1" /></svg></span>').find('use').prop('xlink:href') //undefined
cheerio.load('')('<span><svg ><use xlink:href="#1" /></svg></span>').find('use').prop('href') //#1
```

Since, Safari doesn't support `href` without the "xlink" prefix in svg yet. Maybe, leave `xlink:href` as it was in `cheerio@^0.22.0` is better?

02What counts as reproducing it

The bar, written down before the run.

expected.reportedFailurecommitted with the case
Symptom
cheerio.load('')('<span><svg ><use xlink:href="#1" /></svg></span>').find('use').prop('xlink:href') does not produce undefined; the fix makes it do so.
Expression
cheerio.load('')('<span><svg ><use xlink:href="#1" /></svg></span>').find('use').prop('xlink:href')
Where that came from
Read mechanically from the report's fenced code, SAME_LINE form: `cheerio.load('')('<span><svg ><use xlink:href="#1" /></svg></span>').find('use').prop('xlink:href') //undefined`.

03What happened

No failure was captured.

Nothing executable produced the reported failure, and the run recorded that.
