There seems to be an issue with the test coverage report flagging partial coverage in the Layout, SiteLayout, and CarbonAds components. This PR doesn’t include any changes to those components, and they currently don’t have associated test files. For now, I’ve added the /* istanbul ignore file */ directive to them for preventing the flagging. These components are part of my upcoming tasks in the program and will be tested and adjusted in my next PRs
