Looks like the test needs to be updated for WASM. The SIGSEGV on macOS is more concerning though.

@madsmtm Any insight into this segfault?

Hmm, yeah, that is troubling, I'm looking into it.

Oh, I thought I had migrated softbuffer to use objc2 already, it would've prevented this issue...

The issue is fairly simple once you see it, both CALayer and the window reference are not retained (in part due to servo/core-foundation-rs#643), so I think the window ends up being double-freed (or free'd before the CALayer has a chance to release it's own reference to it).

This is unfortunately not going to work on Wasm, because Window::inner_size() will always return None on Window creation. You have to wait for a Resized event for that to work properly.

I guess this is an issue in winit-test, see notgull/winit-test#11.

Just leaving this here as another argument for notgull/winit-test#11: my system needed longer to work correctly.

The test was removed as part of #214, so I'll close this PR. We will revisit this in the future.
