Hello!

On the Nobel Prize ECG game at https://educationalgames.nobelprize.org/educational/medicine/ecg-ruffle/ecg.html some text areas with scrollable text at the bottom of the screen doesn't work. It is not possible to scroll and read the complete text.

I'm fairly sure this is due to #1033. It's a problem on some sites I maintain as well.

Edit: In case anyone's curious, the sites are:

1) http://www.dnai.org/timeline/index.html - Issue on many biographies, but the easiest reproduction steps are if you click 1950-54, hover your mouse over the right side of the animation so it scrolls, and then click the image of Francis Crick, you'll see a biography that gets cut off and cannot be scrolled due to a non-functional scrollbar.

2) http://www.insidecancer.org/ - If you click "Causes and Prevention", then "3", then "→", you'll see a legend that also gets cut off and cannot be scrolled due to a non-functional scrollbar. Also, there are up and down arrows on transcripts next to the videos on other slides (which themselves don't work due to lack of codec support, though they produce sound) that I believe are likely also using scroll properties, as they do not work either.

Ultrasounds Scrollbar Not work fix please?

Agreed. #4827 almost fixed the scrollbars here, but there seems to be a case where, if the length delta is not large enough, the text pane still won't move. So in this example, it works perfectly now on the Gallery page, but not on the About page.

Filed #4847 for the Ultrasounds thing. It's not related to #4827: that fixes the case where the text is assigned to a textbox after creation. In Ultrasounds, the textbox already has the text.
