When opening a new Google doc in Firefox, webfonts are loaded repeatedly. With userfonts logging enabled the 'Lato' font is loaded 209(!!) times while opening a *single* new Google doc. This is without editing or otherwise interacting with the document. Steps: 1. navigate to Google Drive https://www.google.com/drive/ 2. log in 3. Click on New > Google Docs Result: new Google docs window opens and two faces for 'Lato' are opened 209 times. Expected result: each of these faces are loaded once. There is of course the possibility that this is a Google Docs coding error but for now I'm going to investigate this as a Firefox bug.
Guessing this is related to changes made for the Font Loading API.

Does this still reproduce?
