nil pointer deref when using dispatch

Getting a nil pointer deref here:

Line 217 in 5a14030

f()

I have no idea how to reproduce this, I've been getting this for months randomly and I can't narrow it down or reproduce consistently.

We use webview.Dispatch to evaluate code that sends RPC responses to JS land (we built our own RPC ontop of webview RPC because we needed async procedures).
This works without issues 99.999% of time, until it doesn't and crashes.

According to our observations, this might be related to navigations? We do "reloadless" navigations in our SPA and crashes seem to happen frequently imminently before/after one.
