Resolve "Tooltip for "View file" shows raw HTML"

What does this MR do?

Fixes unescaped HTML content in the button tooltip by removing the HTML content. The previous implementation was using the generated text as the button text hence there was a HTML escape in place. Since we show it in the tooltip, we really don't need the HTML content.
