Start11 taskbar buttons lower border not clickable

In the original Windows 11 taskbar if you move the cursor all the way to the bottom edge of the screen (if  the taskbar is docked to the bottom), to the last pixel, the taskbar buttons are still clickable. And it's convenient, because you can simply move the cursor with one generous swipe all the way down and then left/right to the button you need (by checking if a button is highlighted) and click it. But in Start11 there is like a 5-pixel gap between the clickable area of a button and the screen edge. So you need to move the cursor all the way down AND A LITTLE BIT UP to make sure you are not in this dead zone, or move the cursor more carefully and slower, so it's less efficient.
