Really long text widget disappears

Hi! I’m relatively new to UI widgets and I have a problem with a simple static text widget. It has a few hundred lines of text because It’s meant to display credits. A simple animation changes it’s y position but the text disappears. This also happens when i just move in my design window to the bottom of the text. This can be solved easily by splitting the text section, but I was wondering is this a bug or a limitation?
