Description:
This PR stops loading a website if we detect a possible DoS attack via the location.reload() method and shows an error to the user.

Steps to test this PR:
Test on low (<24) and high APIs (>24)

DoS website stops loading and returns error

1. Navigate to http://ddgdos.000webhostapp.com/dos.html
2. The website should stop loading within a few seconds and show a Snackbar error.
3. Click on reload.
4. The Snackbar should disappear and the website should try to reload.
5. The website should stop loading within a few seconds and show a Snackbar error again.
6. Do a search or navigate to a different URL.
7. The new website should load as expected and the Snackbar should disappear.

Website with internal reloads works as expected

1. Navigate to facebook.com and log in.
2. Search the logout option and logout
3. Website should load correctly.
