🎯 What: The
_mergeOptionsfunction insrc/dotwave.jslacked test coverage. Amock-browser.jshelper was added to run tests in node without DOM APIs throwing errors.📊 Coverage: A new suite
mergeOptions.test.jstests default option overrides, undefined fallback, handling of falsy options correctly, and ignoring unlisted option keys.✨ Result: Test coverage improved for internal utility method
