I'm also seeing this in 1.20.1. I don't know which side is at fault. I got around it by switching to advanced tooltip methods and specifying lines.
tooltip.addAdvanced('reinforced_deepslate', (item, advanced, text) => { text.add(1, 'Witherproof') text.add(2, 'Mineable with a Netherite level pickaxe.') })
