[Bug]: "Do you want to download File.bin" dialog triggered when visiting Raydium.io/swap

Describe the bug

Visiting Raydium.io/swap in the in-app browser triggers a dialog that says "Do you want to download File.bin?"
This does not happen when visiting the same site on Phantom's in-app browser.

Expected behavior

Same behavior as Phantom where there is no prompt for "Do you want to download File.bin?" when visiting Raydium.io/swap

Looks like it's related to my changes in WebView. I'll fix it

Hello @Tyschenko, I found the same message and a really similar one when trying to do ramps operations with specific providers (Mercuryo and Ramp Network): https://www.loom.com/share/70d667f963cd430baa0e649766481e28?sid=91b9cc36-7339-47e4-b9b8-0ef75f280384

I was on Android when doing this, using build 2043.
