Bugzilla

[This](https://searchfox.org/mozilla-central/rev/38652b98c6dd3bf42403eeb8c5305902b9a6e938/mobile/android/geckoview_example/src/main/java/org/mozilla/geckoview_example/GeckoViewActivity.java#1344) seems to be the only location we cover it. And only if `hasSession` is `false`... which I presume is not the case if we're switching to a loaded tab? From a quick search of the code we seem to always pass a non-null session, meaning we don't cover it.

(Also, is it a bug that we always cover WHITE there instead of it depending on the theme?)

In android-components they call it [here](https://searchfox.org/mozilla-mobile/rev/c8ec80d154917909a0cfe402d7cb895af469fe67/android-components/components/browser/engine-gecko/src/main/java/mozilla/components/browser/engine/gecko/GeckoEngineView.kt#81). They set a different colour there depending on the theme, but we don't cache that. Should we be caching the colour and using it whenever geckoview itself decides to cover?
