When I selected a text range, the anchor move around. I disable all other extensions, but the question still exists.
I thought the question is in src/mirrorCursor.ts. the window.onDidChangeTextEditorSelection was called multiple times while I selected a text range. It's parallel.
Then in event handler, it calls exitMirrorMode which change selections.
So when I selected a range of text quickly, anchor will go back to the charator I selected before. And if I click on other position, the anchor will move around the whole page.
Sorry for my poor English. I have tried.
