Currently the minimum amount of space between the sidebar and the content is ~68px. This only becomes apparent when the browser window is smaller than 1440px.
We want to reduce this minimum amount of space to 46px. I believe this change will require us to also update the value of the breakpoint, which is currently 1440px.
- This should be as simple as adjusting the @margin-start-content variable in layout-max-width.less. 
- Note that there is 8 pixels of horizontal padding on the tabs and content. This may need to be factored into the calculation.
