link preload of font files causing warnings in Chrome

MBP El Capitan 10.11.6 Chrome Version 59.0.3071.115 (Official Build) (64-bit) (up-to-date)

This seems to happen the first time Gitter loads up no matter which room I am in. Here is an example of the warnings, all of these are produced from the initial visit to one room:

And looks like its originating with vendor.js:

(anonymous) @ vendor.js:15
send @ vendor.js:4
ajax @ vendor.js:4
(anonymous) @ vendor.js:9
s @ vendor.js:6
o._resolveFromExecutor @ vendor.js:5
o @ vendor.js:5
(anonymous) @ vendor.js:9
o @ vendor.js:5
o._settlePromiseFromHandler @ vendor.js:5
o._settlePromise @ vendor.js:5
o._settlePromiseCtx @ vendor.js:5
r._drainQueue @ vendor.js:5
r._drainQueues @ vendor.js:5
drainQueues @ vendor.js:5
(anonymous) @ vendor.js:5

Not sure if this is a known issue or not or if it would be something worth fixing. I discovered it when I was trying to embed Gitter into a project of mine and thought that I was doing something wrong. When I checked the console on Gitter proper, I noticed it was happening there too and thus not anything I was doing.

Based on what little research I did it looks like this could possibly be fixed by using prefetch instead if there is even some potential that the preloaded resources may not be used right away.

moved from #1751 (closed)

moved from webapp-temp-issues-for-move#10 (closed)

added enhancement label

moved to webapp-temp-issues-for-move#29

Any updates on this? Couldn't really judge the different movements from above.

Can confirm with some research that using prefetch should (probably) do the trick.
