Get the right text out of hyperlinked formula cells by papandreou · Pull Request #552 · exceljs/exceljs
Turns out we actually had one more patch floating around, sorry :)
This one makes sure that hyperlinked cells that contain a formula will have the right text available.
Previously this test would fail with expected undefined to equal 'someone@example.com'. It appears that there wasn't any way to extract the text contents from those hyperlinked formula cells, except for the hyperlinked url.
