Notification doesn't always work with multiple garden builds and media queries

[smahood]

With the following use case, figwheel loads changes to the css properly but does not always show the figwheel notification.

• Building stylesheets using garden and lein garden auto
• 2 separate garden builds
• One of the garden generated CSS files is linked using media="print"

When the CSS files are changed and reloaded, the notification doesn't always display - using the same example project, I've had it working every 2nd time, never, and every time. Not really predictable which will happen.

A sample project, as close to reproducible as I can get, can be found at https://github.com/smahood/figwheel-issue-226

Thanks for the report. Figwheel hasn't been designed with any thought of multiple CSS file notifications.

This is a race condition that can be fixed with some judicious application of core.async. I'm already using for file loading extending this to css loading should be straight forward.
