[Bug] Default domain matching sometimes matches on incorrect domains

[lionel-rowe]

Describe the bug

The default domain matching matches when the domain string is found anywhere within the URL, not only when it's the hostname.

Browser

Chrome 97.0.4692.99 on Windows 10

To Reproduce

Steps to reproduce the behavior:

• Go to https://example.com/ (hostname: example.com)
• Add body { background-color: fuchsia; } as a Stylebot rule for that page
• Go to https://www.google.com/search?q=site%3Aexample.com (hostname: www.google.com)

Expected behavior

Background is default (white)

Actual behavior

Background is fuchsia

Additional context

I'm guessing the problem is here: https://github.com/ankit/stylebot/blob/060f566e49c83847d6c4f7e1b87156d91de63a73/src/background/utils.ts#L34-L37

Replacing that indexOf check with something like new URL(url).hostname === new URL(`https://${subUrls[i].trim()}`).hostname might do the trick.
