[v13.12.3][iOS] Broken loading of JS (and probably some other) assets by web pages in WebView

[birdofpreyru]

Bug description:

Web pages in WebView fail to load JavaScript (and perhaps some other) assets on iOS. Just commenting out didMoveToSuperview implementation makes it work fine.

I guess, if initialization is done inside didMoveToSuperview, the page load begins while the webview is not visible on the screen, and in that case it just does not bother to load JS, as some sort of optimization.

To Reproduce:
