#47641: fix: crash on source capture with empty thumbnail size
Merged
Description of Change
Refs CL:5783826
Closes #47591
Fixes a crash when calling desktopCapturer.getSources with an empty thumbnail size.
DesktopMediaListBase now calls Refresh(false) after dispatching DesktopMediaListObserver::OnDelegatedSourceListSelection, so it's important not to call DesktopCapturer::HandleSuccess (which deallocates the DesktopMediaList) synchronously from OnDelegatedSourceListSelection.
Checklist
- PR description included and stakeholders cc'd
-
npm testpasses - PR release notes describe the change in a way relevant to app developers, and are capitalized, punctuated, and past tense.
