Error using URL object in safari

[dennererthal01]

Configuration:

• Web browser and its version: Safari Version 10.1.1 (12603.2.4)
• Operating system and its version: macOS Sierra Version 10.12.5
• PDF.js version: 1.8.593
• Is an extension: No

Steps to reproduce the problem:

1. Include pdf.js on any html file and load that file
2. Open developer console and paste the following code:
   new URL(location).searchParams.get('param')

What is the expected behavior?
The browser should check if the provided URL has the specified parameter (screenshot from Google Chrome).

What went wrong?
On safari, it changes the URL and redirects it, breaking the page.

@dennererthal01 Did you fix your problem ?

I have the same issue but the fixing PR has been closed.

@GinjiBan currently I stopped using URL().searchParams, which seems to be the only method broken. I'm using both URLSearchParams() and URL().search.

I'm a student at Seneca college learning open source, and I was hoping to work on this bug for my course. If no one else is currently working on it, I'd like to give it a try :)

@St3v3n-D Nobody indicated that they're working on it, so it's yours!

This URL polyfill breaks some other parts of my application - my temporary work-around for this is to include another polyfill after pdf.js is required so older browsers (and safari) are polyfilled twice but end up with a working version!
