How to disable double cursor?

Question

Visual Studio Code

When markup, a second cursor appears. When you activate the cursor in the opening tag, the second one appears automatically in the closing one. If you want to add a class for a tag, it is added in the closing one too. I don’t know how it activated, maybe I accidentally clicked on some kind of op. keys. I did not find anything similar in the combination settings.
Opened / closed several times VS, even a new version came out.
Keyboard is clean. Ctrl and Alt are not pressed.
Everything is fine in css files and other editors.

Answer 1

Most likely there is an Auto Rename Tag extension. Disable if not needed (but here's why?)

Answer 2

Also encountered this cursor. In general, go to the settings, and disable HTML: Mirror Cursor On Matching Tag
