Because the signature is correct in Sent Items, do not rebuild it yet. Check whether Outlook is composing in a different appearance mode: temporarily set Outlook's appearance to Light and disable any message-background/theme option, then create a new message. If the preview changes while Sent Items remain correct, it is a compose-window rendering defect. Capture that comparison with the Outlook and macOS version for Microsoft support.

Can you check whether an update to 16.110.1 (released yesterday) will fix this issue already?

There was an issue in 16.110 which caused Outlook not to properly recognize the sections within an email and didn't include things because of that. That should be fixed now.

Unfortunately, the issue still exists in 16.110.1 - I just updated, no change.
