Description:
Bugfix: When watching a Youtube video (/watch/ page), tapping the buttons in Youtube's top navbar caused the page to reload or DuckPlayer to show, and users were not able to access Youtube's settings.

Since Youtube uses hashes for internal navigation, this allows internal Youtube navigation for all DuckPlayer modes by ignoring URL changes that include a hash (#)

Steps to test this PR:

1. Set DuckPlayer to 'Always Ask' mode
2. Go to youtube.com and navigate to a video
3. Tap the 'Search' or 'Three dot menu' icon at the sites' top navbar
4. Confirm Youtube's UI is presented and page does not reload or DuckPlayer opens
