When filing bugs, if it's an inlining issue, ensure you include full test source to work against.
This can be via a PR or by linking to a gist that include at least two (first) files:
<issue>.src.html<issue>.result.html
When these are put in the fixtures directory, they are automatically tested against.
If there are any external assets the example needs, please also include these and name them with the same root as your example, i.e. <issue>.css or <issue>.min.js etc.
In addition <issue>.opts.json can be loaded to help specify runtime options during the test.
To test a single fixture you can use::
$ FILTER=<issue> npm test
