fix: font face descriptors in chrome 38

[pecoram]

In chrome 38 if some attribute is undefined the font is not loaded

I recommend removing the object.fromEntries as that usually doesnt get compiled correctly on older devices

@chiefcll TBH a lot of features are missing on older devices, like Array.includes, so generally you must include some core-js polyfilling, ideally based on usage as Babel can do.

Although not wrong, if the idea is to make stuff work on Chrome v38 you can easily achieve the same with functionality that we know is available on chrome v38. Avoiding another place to polyfill and providing consistent behaviour, likely get some (albeit super minor) performance increases on the way.

I'm with Chris here, you can easily achieve the same with e.g. a for...in loop, write it to a new array and use that from there on (or replace the original one).

Please replace Object.fromEntries with a for loop or similar, to align with targeted chrome v38 functionality.
