Failed to run Postlight Parser (mercury)

[jangernert]

Describe the bug Trying to run the mercury.web.js dist of postlight parser (aka mercury parser)

To Reproduce

• paste the var Mercury=function() ... dist code into a file
• add the var html_content = ... of a page that can be parsed by mercury
• call the mercury function

Mercury.parse("https://www.phoronix.com/news/Linux-6.2-Rust", {
   html: html_content,
   fetchAllPages: false
   }).then(result => {
       console.log(result);
   })
   .catch(err => {
       console.log(err);
   });

Expected behavior the code running and getting the parsed article

Actual behavior

cargo run -- test.js
    Finished dev [unoptimized + debuginfo] target(s) in 0.13s
     Running `target/debug/boa test.js`
thread 'main' panicked at 'character was not a valid digit', boa_engine/src/builtins/number/mod.rs:611:34
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

but running with RUST_BACKTRACE set to 1 or full yields a different error:

RUST_BACKTRACE=1 cargo run -- test.js
    Finished dev [unoptimized + debuginfo] target(s) in 0.12s
     Running `target/debug/boa test.js`
Uncaught TypeError: cannot convert 'null' or 'undefined' to object

Build environment:

• OS: Fedora Linux
• Version: 37
• Target triple: x86_64-unknown-linux-gnu
• Rustc version: 1.65.0 (897e37553 2022-11-02)

Additional context I currently abuse a webkitgtk webview to do the same thing. So I know it can work. I'm hoping boa will at some point be a better option for me :)

#2863 should fix the panic bug, but the TypeError seems like a separate issue.

@jangernert can you confirm that the panic does not happen anymore on the #2863 branch?

The error thrown is probably a runtime issue, right? We don't define a window object, since that's responsibility of the runtime, and it's the same thing for a lot of the web APIs that Postlight uses.
