2. Flyout's "Apply" buttons were not enabled because the palceholders for "Operator" dropdown were misleading and looked like the values are already selected. https://github.com/Azure/pcs-remote-monitoring-webui/issues/1230
3. TimeFilter was not working because the value was not updated to map the new fluent control https://github.com/Azure/pcs-remote-monitoring-webui/issues/1229
