Pico-8 occasionally seems to forget to select a new line if you've copied something and then create a new tab. Because there is no line selected, pasting seems to crash it

Most of the time a new line is selected after creating and switching to a tab, but occasionally it doesn't. I was able to reproduce although unsure if there's another step (may have to do with switch tabs or alt tabbing).

How do I reproduce this?

It only happens when making a copy of code and pasting it to a new tab and there's no blinking red cursor when switching to the new tab. I can't reproduce it on command consistently. I think there's a missing step.
I noticed that ctrl-a on a empty tab removes the cursor, although pasting works fine. It's only when a new tab is created and doesn't start with a cursor that pasting crashes.
