trying to open pest.rs hangs, consuming 200% CPU in Chromium

[whitequark]

I'm trying to open https://pest.rs in Chromium (Version 72.0.3626.7 (Developer Build) built on Debian buster/sid, running on Debian buster/sid (64-bit)). This never succeeds. The tab hangs and consumes 200% CPU according to the Chromium task manager. I cannot acquire a backtrace because it appears that the Chromium debugger cannot interrupt the loop it is stuck in, for some reason.

This runs fine on Chrome version 71 on macOS, 0% CPU on the pest.rs tab. I would imagine that this might have something to do with that specific nightly build.

To add to this, I realized it could be one of my extensions, but chromium --temp-profile https://pest.rs fails in the same way.

The website has some super-light JS for background generation, CodeMirror as an editor, and pest compiled in WASM. If you want to debug this, you could try to disable each and see which causes the error. (remove the <script>) You can also run this locally with cargo web.

Actually, it has nothing to do with JS. It still hangs with JS turned off. I've narrowed it down to https://pest.rs/style.css...

Oh well. I can't narrow it down any further. Seems to be layout stuck in an infinite loop. I think there's nothing you can do.
