As a user of the Wikidata Query Service, I want the "Execute Query" button to be visible when I'm arriving at a long-text query with many lines and not have to scroll down to find it.
**Problem:**
When arriving from a link to a long-text query,
1. The "Execute Query" button is not immediately visible because it is aligned with the last line in the query form.
2. A scrollbar for the query form is not visible (this is the case only for the mobile interface)
**Example:**
