Bug: Resolve screen toggling error when switching between "suggest a source" and search page

Originally from https://github.com/bitcoinsearch/bitcoinsearch-app/issues/118

The screen kind of moves around when toggling between the "suggest a source" feature and existing it (look at the header). (Only desktop).
