1609292 - Pause-on-exception doesn't catch uncaught exceptions from (wasm? imported?) code?

Status: NEW

(DevTools :: Debugger, defect, P2)

Description

[Kelsey Gilbert [:jgilbert]]

I ran into this trying to debug bug 1609006.

The console was showing what looked like uncaught TypeError exceptions, but the debugger option for Pause-on-exception wasn't pausing on them. Pause-on-caught-exceptions did seem to work. (or at least I was pausing on enough of those that I found the issue I was looking for)

Line 7411 is what should have thrown an error. I could only get there to pause by searching for the string and setting a breakpoint. Only after this, continue paused on the exception correctly.

This test case https://lukewagner.github.io/test-wasm-stacks/ from bug 1460089 seems to work though.
