scroll-with-bottom-base in editor-canvas%

Enables or disables bottom-base scrolling, or gets the current enable state. If bottom-base scrolling is on, then scroll positions are determined by line boundaries aligned with the bottom of the viewable area (rather than with the top of the viewable area). If last-line scrolling is also enabled (see allow-scroll-to-last), then the editor is bottom-aligned in the display area even when the editor does not fill the viewable area.
