Automatic line selection bug

When I click on a line in the Editor and scroll the mouse cursor up or down, MATLAB automatically selects and highlights across lines as in the screenhot enclosed. This started to happen only recently. I wonder if this has anything to do with the latest macOS update 15.1 or the latest MATLAB update 224b.

Technical Support's reply: "Unfortunately, this behavior is not a bug. This is an enhancement and intentional change made in R2024a to make the MATLAB Editor behave similarly to other source code editors (e.g. in VS Code this is called "Scroll Beyond Last Line"). The idea is to be able to write at the end of the file without the content shifting all the time on the screen. Currently, there is no way to disable it." My response: "This doesn’t sonse to me at all. I don’t have anything to write there and hence all the time I have to scroll more than I am supposed to."

Ensure that your mouse button isn't stuck. I haven't seen this issue but if it continues to occur after closing and reopening MATLAB and after you've ruled out any mouse issues, feel free to contact tech support.

Thanks for replying. I restarted the computer. The issue is still there. I reported it at tech support. Update: Tech support says, with the Magic Mouse, this is a known issue. This is utterly disturbing. Anyone using a magic mouse on a macOS should be having the same problem. That should be thousands of people. I wonder how all these people can wait until the next release.

Why not make this optinal. I do not get what this huge white space is for...
