Crashed When use load-extension with content_scripts

Describe the bug i found you add content_scripts support from 120.0.6099.0, but i not work, it will cause render crash. i test the extension in chrome, it work ok.

To Reproduce Steps to reproduce the behavior:

build master branch cefclient
run cefclient.exe cefclient.exe --load-extension=E:/extension/sample

in the demo the manifest.json file look like this

{
"content_scripts": [ {
  "all_frames": true,
  "js": [ "content.static.js" ],
  "match_about_blank": true,
  "matches": [ "http://*/*", "https://*/*", "ftp://*/*", "file://*/*" ],
  "run_at": "document_start"
} ],
"manifest_version": 2,
"name": "sample",
"version": "1.1"
}

and content.static.js code like this console.log("content.static")

then, we will got a render process crash like this: crash at ExtensionInjectionHost::CanExecuteOnFrame the ExtensionWebViewHelper::Get(render_frame->GetWebView()) will return nullptr:

i try to fix it by:

diff --git extensions/renderer/extension_injection_host.cc extensions/renderer/extension_injection_host.cc
index d1cf50d7c6be2..195fb0119bfd1 100644

   if (!outermost_origin) {
     outermost_origin = render_frame->GetWebFrame()->Top()->GetSecurityOrigin();
   }

but I want to know why it works in chrome

Expected behavior the page and extension loaded success.
