Remove css nowrap from body

[giovanniTramonto]

This sets document white-space back to normal (collapsed).
As mentioned in #1932 (comment) I would recommend this. IMO it’s better for responsive behavior and avoids many overrides in the tree, since in most cases nowrap is an exception.

While I agree with the general idea, I am afraid of lots of subtle consmetic breakages, in list items, axis names, source names, etc. This affects a very broad range of elements.

Understandable. At the same time I was surprised how little the impact was. The only critical part I found was inside dialog layouts, like here https://github.com/googlefonts/fontra/blob/main/src/fontra/views/editor/editor.js#L2413
Those I did not change

I started to do an extensive UI test. Will add results soon

I tested varied scenarios with long placeholder text as well as interactions.
Screens are named by section and branch (--feature or --main).
In total I found 4 differences: 3 bugs (marked red) and 1 potential improvement IMO (marked orange)

Screens are here https://drive.google.com/drive/folders/1yEHHulq3416DBPKfgLknFLFV5WVvcOB1?usp=sharing
