1. Open the browser with a new profile
2. Navigate to twitch.tv or vimeo.com
3. Open devtools (console tab)

Actual result

No "script loaded" messages should appear in the console.

Reproduces how often

Brave version (brave://version info)

1.69.160 Chromium: 128.0.6613.114 (Official Build) (x86_64)

It turns out that GL scripts are loaded for all sites for both Rewards-enabled and Rewards-not-enabled users. This is primarily for historical reasons (the scripts used to insert tip icons).

This issue will be addressed by #40872 and #34237.
