Experiencing CSS/iScroll Load racing issue

[iDVB]

I narrowed things down to something to do with chunk-injecting the css in webpack. If I use ExtractTextPlugin and all the css goes into a single file, everything works fine. But if I don't use that, and it blobs each css in, it does not work "on first load" ...works fine after that.

Additionally, if I put inline style on the parent item around the then that works too.

I'm curious why that makes a difference.... doesn't the CSS always load 100% before the JS does?
