1239197 - pathological reloading of webfonts opening new Google doc

Status: NEW

(Core :: Graphics: Text, defect, P3)

Description

[John Daggett (:jtd)]

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.

Attachment: userfont log opening new Google docs document

Lots and lots of "userfont rules update" modifications...

Does this still reproduce?
