💡 Description

• The crash was occuring while dragging and dropping a quick search engine after the "Add Search Engine" button (this being an action that should not be permitted) causing the quick search engines array to go out of bounds..
• This PR adds a guard statement to make sure that we remain in the same section (quickEngines) during drag&drop actions.
