Range slider prevents shifting of axes

plotly.js
1

Using range slider makes the yaxis 1 non draggable whereas the yaxis 2 can be shifted up and down to move the line in appropriately (see the cursor ns-resize).

Are there any settings that can make the yaxis 1 draggable as well?

Thanks for reply!
