If I have two windows side-by-side in the dwindle layout, with a spliratio greater than 1, then although I can move the right window to the left with hl.dispatch(hl.window.move({ direction = "r" }), I cannot do the same from the left; if splitratio is left than 1, then it is the other way around. Why is that ?
