Truncated JS stack traces?

I have a React JS app compiled with Webpack, complete with source maps etc. When I expand a stack trace for an error in Chrome devtools console, I see a trace going back through 20+ functions over multiple modules. However when I look at the same trace in a Sentry Event view, I only see the last 5 (this is for an event captured with captureException btw).

Is there a way to expand this and get the full trace? …or am I doing something wrong?

Cheers!
