Shift of focus when script creates window.

I have noticed a difference in behavior between R2018b and R2021b.

When running a script with cells which creates a figure (undocked), in R2018b the focus stays with the script, so I am able to continue to the next cell/section using Shift-CMD-Return. In R2021b the focus moves to the figure window, so I have to take my hands off the keyboard, find the mouse, click on the Editor window, then use Shift-CMD-Return to run the next cell. This is a really annoying.

How do I revert to default behavior of R2018b?

I don't think it's the version. I notice that sometimes (in r2021b) I can batch process images and switch away and work in another program just fine with no focus stealing. However sometimes I can't because my MATLAB app steals focus back for some reason.

I haven't been able yet to figure out exactly why but I think it has to do with me interacting with the editor window. Like if I just run it, then there's no stealing focus but if I set a breakpoint in it or something like that, then it will steal focus every time it has to update the display, like with axes(), figure(), or imshow() or something. So I just try to avoid doing anything with the editor once I open the code -- I just run it immediately. Sorry, I wish I knew the exact reason why it steal focus or not.
