TYPO3 Core

There is a warning in current master due to $parts being false instead of an array.
Accordingly, to preg_split docs, that means there was an actual error, not that it didn't match. So an easy type cast might be wrong here. Instead we should find the cause of the error.

The issue is caused by ./vendor/bin/typo3 referenceindex:update with following content:

<p>Nice to have:</p>
<ol>    <li>Add further tests</li>      <li>Check out <a href="{softref:5ab0deeea5faa1691e4d2b36b61a6105}">https://github.com/benjaminkott/syntax</a> and add proper syntax highlighting with defined code language to CKEditor. Just keep rendering via Server.<br />      pre tag parsing, add language, e.g. as attribute in RTE, extract and use it as config</li>      <li>Add <s>link list to</s>

And it looks like the issue was introduced in one of these commits: https://github.com/TYPO3-CMS/core/compare/293fa45605a994be4e83a6a509046a18e9582c44...7909d6d3109d0b7c5caaaf7a80c61ca20ba6c4b7, most probably: https://github.com/TYPO3-CMS/core/commit/608498f7c02550b0c37888ce43a76cd72d5198a0.

But I can't find a difference in the code.
