Fix issues with RequestBlockingScript.js

[cuba]

Description

The request blocking script does not emit all the required events that would normally get emitted if content was blocked using the content blocking manager. This causes issues with pages such as youtube forcing us to add a exception rule for youtube

Steps to reproduce

1. Add a custom rule '||youtube.com/youtubei/v1/log_event?' (wait a few seconds for this to compile)
2. Click on many videos (maybe 50) (you don't have to watch them just click on them)
3. Refresh the page

Note: Alternatively you can inspect the web page and see if log items are being removed from the LogsDatabaseV2 as you navigate videos (this saves you from clicking on tens of videos)

Actual result

Page is stuck loading as youtube tries to dump its log queue (unsuccessfully) This happens on every refresh.

Expected result

Page should have normal loading delay
