Interrupted resizing of window

When making the windows narrow, the resizing stops at a width around the position where it has switched to Stacked layout mode.If you stop resizing and try again, then it will allow to resize it smaller.Is it possible to make this smooth directly to the minimum width?

Screen recording.
