Custom search drawer tab - two "reset" buttons instead of one

When configuring:

• Nuxeo 9.10 (HF45) + WebUI
• 1 page provider in Modeler
• the associated pageprovider form and results in Designer
• the default associated drawer search tab
• start Nuxeo, deploy the project, launch a search, save the search, fetch the saved search

1 grey "Reinit" button appears above the normal "Reinit" and "Search" button

Expected result; the "normal" Reinit" button should be enough or the role of the second button should be explained
