✨ Scroll and cursor position in file are lost when switching to another file and then back

### Description

When you navigate inside a file, then you go to another file keeping the previous one open and when you get back to the first file, the scroll position and of the cursor location in the first file are lost, so it automatically shows up the top of that file.

### To Reproduce

1. Open the file a.cpp and navigate through it so you go to a specific cpp function inside that file.
2. Open the file b.cpp in another tab while keeping the file a.cpp open in its tab.
3. When you get back to the opened tab of the file a.cpp, you are redirected to the top of the file a.cpp.
So when you are focusing much on a specific function in a.cpp and just wanted to check something related to that in b.cpp, when you get back to the open tab of a.cpp, you completely lost the position of the cursor on the function that you were working on.

### Expected Behavior

The position of the cursor in the open file that you left open in a tab for a while should be the same when you get back to it.

issue 中没有指定文件或测试。首先在 CodeEdit 中复现标签页切换流程，并跟踪打开文件的光标和滚动状态在哪里处理；完成标准是返回之前打开过的文件时，两个位置都能恢复。
