The version of style-loader we are using has a known bug for setting the media attribute on style tags webpack-contrib/style-loader#458
There was a problem hiding this comment.
This is a work-around that instead uses the MutationObserver hacked into core for updating media attributes based on the presence of the data-print-media-style. The result of this is the print styles "flash" once as they are applied by the browser until the MutationObserver kicks in. Very hacky, but work-around for rather not updating style-loader + webpack to latest version.

Summary
Demonstration (focussing on the
dashboardplugin) of how we might leverage browser printing functionality for creating PNG or PDF reports. This will enable users to print certain pages of Kibana in their browser rather than requesting a report from the Kibana server.If this work succeeds it may have far-reaching implications:
pdfmake, and instead utilise existing browser functionaliyWith this PoC we want to establish that we can:
