4. The scrollbar doesn't move.

OBSERVED RESULT

ADDITIONAL INFORMATION
This issue is specific to the chat scrollbar and can't be reproduced in other locations, like the settings dialog.
It might be related to the right information panel, which can be shown either by clicking the top right button or by dragging the mouse to the left.
In fact, every time the scrollbar is 'blocked', if the cursor is moved to the left, the room info panel appears. Otherwise, the scrollbar will be moved and the info panel won't show up. This may indicate that the sliding gesture intended for touch screens could be interfering with the scrollbar.
