Bug: After moving Selection, the small keyboard does not automatically pop up and cannot continue editing

Hello, I want to implement a custom image using DecoratorNode. However, I found that if there's only one Image node under the root element, it's quite difficult to insert content before or after it. I discovered that enabling the BlockCursor can solve this issue, but I encountered several strange behaviors during my usage:

1. When clicking on the blank area of the editor, the BlockCursor does not appear automatically. It only appears if you select the image and then switch using the arrow keys.
2. I tried using RangeSelection to show the editor's built-in BlockCursor, but I found that even though the BlockCursor moved to the correct position, I still couldn't input content (the virtual keyboard didn't pop up on mobile devices). Only after clicking again could I focus and input content.
3. click image，the virtual keyboard did not pop up when focused
