Subject: [PATCH] Fix `accept` for SVG files in `file` uploaders: (#1732)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using `accept: 'image/svg+xml' to only allow SVG file to be uploaded should now work.

The `preg_match` was comparing `svgggg…xml` with `svg+xml`.

Check the [List of Media Types](https://www.iana.org/assignments/media-types/media-types.xhtml#image) for more potential issues.
