== Symptom
The TextExtracts API only returns the first sentence for [Egyptian Weasel on the Beta Cluster](https://en.wikipedia.beta.wmflabs.org/wiki/Egyptian_weasel) when the `exsentences` query parameter is set (when there are 2 sentences). Compare the result of the following two API requests:
# https://en.wikipedia.beta.wmflabs.org/wiki/Special:ApiSandbox#action=query&format=json&prop=extracts&titles=Egyptian_weasel&exintro=1
# https://en.wikipedia.beta.wmflabs.org/wiki/Special:ApiSandbox#action=query&format=json&prop=extracts&titles=Egyptian_weasel&exsentences=5&exintro=1
The following text is omitted:
"It is rated "Least Concern" by the IUCN Red List." is omitted from the text extract.
== Possible cause
Returning the first line of the extract seems to be the default behaviour of `ExtractFormatter::getFirstSentences`, i.e. the regex that we're using isn't matching the content of the page.
