Thanks for reporting Thomas. This looks to be a regression introduced when the table functionality was changed to use input elements rather than text areas when there's only one line per cell - around August this year.
It's fixed in the development branch on github - you can pull just the files amd/src/ui_table.js, amd/build/ui_table* and purge all caches if you're desperate for a fix. Otherwise I hope to push all recent updates to master and to the Moodle repo by Christmas.
