Summary

FPD does not work with Javascript JIT disabled (chromium).

Setup

Pages affected: all pages
JShelter Version: 0.21
Browser: ungoogled-chromium

How to reproduce

1. Launch chromium with --js-flags=--jitless OR set "DefaultJavaScriptJitSetting" policy to 2.
2. Open https://browserleaks.com/canvas

Expected result

FPD reports moderate fingerprinting. Report window shows APIs that were called.

Actual result

FPD reports none or negligible fingerprinting. Report window is empty.

Is this a JShelter problem? Or how can I keep JShelter working with disabled JIT?
