To be able to use InitScripts without Runtime.enable, Patchright uses Playwright Routes to inject JavaScript into HTML requests.

Playwright Routes may cause some bugs in other parts of your code. Patchright InitScripts won't cause any bugs that wouldn't be caused by normal Playwright Routes.
If you want any of these bugs fixed, you'll have to contact the Playwright team.

Patchright InitScripts can be detected by Timing Attacks. However, no antibot currently checks for this kind of Timing Attack and they probably won't for a good amount of time.
We consider them not to be a big risk of detection.
