DOC: try using non-breaking spaces in nav bar

This may help the responsive layout to avoid things like matplotlib/matplotlib#28832

You could more easily achieve this using text-wrap: nowrap; CSS.

That said, text wrapping is not the problem of #28832. In fact it rather helps a bit. The main issue that there is not enough space for all the content when shrinking the page width. This leads to wrapping, and the wrapping that consumes the most vertical space are the icons:

To fix this, we either need to hide the menubar earlier (i.e. override this setting

) or, - more elegant but also more complex - we have to somehow condense the icons (e.g. into a dropdown) for the intermediate widths.

We should probably just adjust the width for the collapse? I'm sure they chose a width based on their toolbar and ours is pretty "feature full"/"cluttered"

That's the sass setting I've linked above.
