[otrs] SpellCheck on 2.4.4

Hi, I upgraded from 2.3.4 to 2.4.4, the config was such that an agent couldn't send an email without spell checking it but it still allowed the agent to send it out with unrecognised words (like names). On 2.4.4, it forces the agent to spell check but doesn't allow the agent to send the email unless all words comply. Is this a bug or expected behaviour? Thanks, Josh.
