Alpha textures show up white when loaded from bundle

We upgraded to 2019.3 Standard Pipeline, from 2019.1 LWRP, and one thing we noticed is that our alpha/transparent textures load in as solid white from a bundle. It basically looks like it is ignoring the Alpha channel.

Before bundling, the texture looks perfectly fine in the Editor. Once loaded in and incorrect the texture will go back to normal if you reassigned the same shader to the material.

It also only appears to happen in the Editor, and if we make a build the textures display properly.

Is this a known issue? There are worries this will eventually leak out into the actual build and cause problems.

Thanks.
