EDITED: The problem is the Enter key, not the Spacebar as I had originally reported.
Okay, you all are going to think I've finally lost it. But this has happened to me enough times that I know it's real. More importantly, I'm certain it's not user error.
Reproducer steps: In Mail, open a message. Press Command+R to reply. Type the first sentence of your reply. End the sentence by pressing a period. Press the Enter key to start a new paragrap. Then type your second sentence.
Sometimes but not always (very rarely in fact, and not at all reproduceable), the Enter key following the period is ignored by Mail. The result: Your second sentence starts immediately after the period with no intervening line break.
Anyone else? I mean, if at least one other MacOS user is seeing my solidus issue, then I figure there's got to be someone beside me who is experiencing the mysterious missing-space-after-first-period-in-email-replies issue.
It's likely, even probable, that this is VoiceOver related. I have "while typing speak" set to "characters and words", so I expect to hear "period" right when I press it. But, when typing replies in Sequoia Mail, I sometimes experience a slight delay before VoiceOver announces the period character. Whether these two issues are related or not, I don't know. But if VoiceOver has one problem with periods, it probably has others.
Yes, I opened a feedback report.

Possible cause
I have noticed that the issue occurs when I'm replying to an email message that contains a question. Here's what I think is going on.
Someone sends me an email with a question. I press Command+R to reply. Unbeknownst to me, Mail has created a dialog with generic auto-generated reply text. Focus is, well, I don't know where. I can type into the message body, but after the first sentence, either spacebar or Enter or both are being devoured by that little generic response dialog. I need to exit out of that, then go back and press space or enter or whetever was missed.
Turn off suggested replies
I hope this helps someone else.
Go into System Settings, find Spelling & Prediction (no idea where it is, I found it with the search box), and turn off "Show suggested replies."
re: Mail sometimes skips Enter key
There are times when talking to yourself is the most intelligent conversation you've had all day. & this 1 has the potential to help others, if they actually search the forums first before rattling off their question. Good job, Paul! :). Sending warmest wishes & prayers Colorado way.
I've seen the same thing in messages.
If there are suggested AI replies, pressing enter doesn't send the message.
Since enter doesn't send messages in mail, I'm guessing that you can't type new lines? if so, I really think that should be fixed.
