Dashboard x-axis slider clipped

I have trialed a few of the other sample dashboards and have found it is the x-axis range slider that is causing the issue of clipping.

This is also causing the problem in my other post (Resizing Dash to fit a parent container)

So now my question is:

Is there a way to resize the x-axis range slider?

In addition, when inspecting the elements, it seems to be appended to the bottom of the html document, ignoring the bounds of the html doc (see attached image). How do I get Dash to respect the bounds or will this require some redevelopment of the tool?

P.S great app , I am quite excited about Dash.
