`<twisty-alg-viewer>` Avoid line breaks inside Square-1 tuples.

[lgarron]

To Reproduce Steps to reproduce the behavior:

1. Go to https://scramble.cubing.net/?event=sq1
2. Resize the window.
3. Move tuples like (5, 4) will get split on spaces.

Expected behavior Move tuples should stay together. This should be possible with a few lines of CSS, although we'll have to expose a way to ask a Grouping if it's a Square-1 tuple.
