Typing in the textarea of "Edit Page" with a long content keeps reset-scrolling on every key stroke

When I have a long-enough page that exceeds the height of the browser screen, typing any character makes the scrollbar to reset to the top and goes down.
This makes it almost impossible to write contents, unless I manually remove input event listeners of the textarea element in the browser's developer tools.
