Height Change During the Session Causes Cursor Y to Jump to the Wrong Position

[nikitaeverywhere]

WebTerminal v4.2.8, steps to reproduce:

1. Minimize the WebTerminal window to take 50% of the maximized height;
2. Press until the output reach the bottom of the window;
3. Enter write "test" but do not press <Enter>;
4. Maximize the window and press enter.

The output goes in the wrong position then. The same happens if you enter, for example, hang 10 write "test", and maximize the window during the hang.
