MacOS messages app not active when I swipe screen and back

I think this started with Ventura. Maybe Monterrey. But it is only a problem with the Messages app. But if I am in the middle of typing a message, and then I swipe away from that screen to look at something on another full screen (like Safari), when I swipe back to my main desktop with Messages, the app appears to be the active app with a blinking cursor and everything. However, if I start typing again, it doesn't show up in the text box. Even more strangely is that my typing is registering, because autocorrect options will show in the text box even though there is no text.

This is minor in the grand scheme of things, but I just have this habit of swapping back and immediately typing, and then realizing a sentence in I have to reselect the box and retype everything. ¯\_(ツ)_/¯

Also, it does appear to be a bug, because it doesn't happen that way with any other app.
