Demo extension: https://jeurissen.co/webext-demos/webrequest-for-frames-in-popup To reproduce, open popup in new tab. In Safari, the webRequest.onBeforeRequest listener reports resource type main_frame, while it should report resource type sub_frame.

This issue can still be reproduced in Safari Version 26.5 (21624.2.5.11.4) Made a simplified demo extension which showcases this issue is not restricted to onBeforeRequest but applies to all the webRequest events: https://jeurissen.co/webext-demos/webrequest-type-sub-frame
