Fix page_description helper performance This helper is used for extracting part of the issue / MR / whatever description for use in the description meta tag: 1. To do that, we look at the source of the Markdown description. 2. We then strip out all HTML tags. 3. And then take the first 30 words. Doing that can be really slow - especially as Markdown is supposed to be treated as plain text. There are many better ways to do this, but the immediate performance fix is to swap steps 2 and 3. This does mean that the description may be less than 30 words (or even empty), but it is much faster when the description is very long. 2019-05-22 10:30:10 -04:00			`---`
