AboutWelcomeTelemetry.sys.mjs	Attach browser attribution data to a ping payload. It intentionally queries the cached attribution data other than calling `getAttrDataAsync()` in order to minimize the overhead here. For the same reason, we are not querying the attribution data from `TelemetryEnvironment.currentEnvironment.settings`. In practice, it's very likely that the attribution data is already read and cached at some point by `AboutWelcomeParent`, so it should be able to read the cached results for the most if not all of the pings.	12267	97 %
AWScreenUtils.sys.mjs	Filter the given screens in place with a predicate. @param {object[]} screens - The screens to filter. @param {Function} callback - The predicate for filtering the screens.	3067	97 %
