Bug reports:

I'm using Quasar framework (latest version) but when I try to screen my page with html2canvas, everything is perfect excepted icons (who comes from Material icons). See : https://i.imgur.com/HH9ojJx.png

Exemple :

                round
                size="sm"
                :loading="loadingScreenshot"
                color="negative"
                @click="capturePage()"
                icon="photo_camera"
              >          ```
Icons are remplaced by their name...

### Specifications:

 * html2canvas version tested with: 1.0.0-rc.5
 * Browser & version: chrome/firefox
 * Operating system: Windows
