Some page elements will disappear when using find

[chang-wd]

Issue Description

When i was using find to search text in Airflow DAG page, all text elements will disappear suddenly. After that, the Chrome default search[CTRL + F] also can not get any search result from the page.
In my opinion, i think the the reason is the page type, beacuse when i search on other type pages, everthing is fine.

Steps to Reproduce

• .It might be a bit hard to reproduce this problem, because you need to have Airflow installed.
