Preview locking make rendering unsuable when working with math

using v3.0.3, preview locking (the preview is locked to the editing tab), make the editing window shift vertically and have unfortunately sometimes the position of the cursor above the top of the page hence we don't see what we type anymore. The shifting of the editing window is very distracting and makes the editor barely usable while the preview is being updated. Why does the editing window should be shifted ? only the preview window should be updated IMHO, no ? The only solution I found was to remove the preview for now but then I cannot check the correctness of the math rendering.

I attach a video of the issue.

As a workaround, you can uncheck "Scroll Editor With Preview"
