LibWeb: Pass correct values to would_start_a_number()

Browse source 
This fixes the crash that Luke found using Domato:
```css
. foo {
    mso-border-alt: solid  .-1pt;
}
```

The spec distinguishes between "If the next 3 code points would
start..." and "If the input stream starts with..." but we were treating
them the same way, skipping the first code point in the process.
