vscode git checkout branch bug

Issue Type: Bug

在工作区中以文件夹的形式放入两个项目A，B分别处于不同分支branchA，branchB，然后将项目A切换到branchB分支，此时A，B项目都处于branchB分支，此时切换A项目到branchA分支，问题就出现了，B项目也会同时切换到branchA分支，我明明只切换了A项目，但是它会影响到B项目。

Put two items in the workspace in the form of folders, itemA and itemB are in different branches branchA and branchB respectively, and then switch itemA to branchB branch. At this time, itemA and itemB are in branchB branch. At this time, switch item a to branchA branch, and the problem occurs. ItemB will also switch to branchA branch at the same time. I obviously only switched itemA, But it will affect itemB.
