Math formulas are broken.

Description

Math formulas (SVG images) seem to be broken currently.
Upon first glance, it has something to do with our OkHttpWebViewClient, which we use to override the WebView's requests for content and images. If I disable this custom client, things work correctly again. Is it something related to the headers that are sent back by the server that we intercept? Has something changed recently in the way that the server responds when fetching SVG files?

Looks fixed on 2.7.224-alpha-2018-01-10. Tested with the tangent article. Side scroll on long formulas works as well.

Works for me too on Nexus 5 (6.01), Wikipedia 2.7.224-alpha-2018-01-17 (also tested in the Tangent article)
