How to load (and use) italic fonts? #433

I'm trying to load Lora both normal and italic at different weights.

Normal font can be loaded using the family Lora:400,... shouldn't the italic version be loaded using Lora:italic:400,...?

Doing so I receive http error net::ERR_ABORTED 400. I tried appending :italic, :ital and :i.

I can see weights and style can be concatenated (i.e. bi) but in my case I would prefer to define the weights as numbers. Is there a way to concatenate weight numbers with style?
