[internal] re-enable RenderDocument

Open dgozman opened this issue 3 months ago • 3 comments

RenderDocument feature breaks isolated worlds - it reports an extra utility context, and so using it right away results in an error.

Commit that enabled RenderDocument: https://chromium.googlesource.com/chromium/src/+/c35065f7e612e3becbe7f24baaca28c7859b7543

Failing tests:

[chromium-library] › library/chromium/js-coverage.spec.ts:66 › should report scripts across navigations when disabled
[chromium-page] › page/frame-evaluate.spec.ts:45 › should dispose context on navigation
[chromium-page] › page/frame-evaluate.spec.ts:55 › should dispose context on cross-origin navigation
[chromium-page] › page/page-goto.spec.ts:828 › should return when navigation is committed if commit is specified
[chromium-page] › page/page-wait-for-navigation.spec.ts:63 › should work with commit
[chromium-page] › page/page-wait-for-url.spec.ts:52 › should work with commit
