Basically, adds the spacing that is otherwise included by the tab protection (which is about 4dp less than the spacing that was previously being added). Adds a compile-time flag to render the header at all times to help visualize issues like this in the future. Check the screenshots below to see some examples of this. Screenshots: https://drive.google.com/drive/folders/1n4wwtjMwOR-eDIE1xAoG3oLXO7txpoT_?resourcekey=0-WP0RNbp7vFh2Yw1wUBZTaA&usp=sharing Bug: 240672593 Bug: 243728487 Test: Manually checked search transition, scrolling behavior, and highlight of the search results with and without a work profile.
