Html mirror cursor also cause line-wise operation (e.g. `yy` `dd`) duplicated

Describe the bug
With the html mirror cursor feature, we will have a paired cursor on the paired tag when we move our cursor into one tag.

I found other issues #4402 reported this will cause visual mode error. And also if you use yy or Y to copy this line, it will be duplicated. Or when you use dd the line and the line below will both be deleted.

The html mirror cursor feature maybe should be treated differently from the plain multiple (two) cursors, it may cause many errors as two cursors, I think.

Does anybody know other strange behaviors with this feature?

To Reproduce

1. Move the cursor to one html tag.
2. Type yy and p or dd

Expected behavior
Only one line should be deleted or copied.

Environment (please complete the following information):

• Extension (VsCodeVim) version:
• VSCode version: 1.41.1
• OS: Microsoft Windows [Version 10.0.18362.535]

Reproduce the issue in VSCode with the HTML mirror cursor enabled, then try yy followed by p and dd as described. Trace the HTML mirror cursor and line-wise operation entry points; done means yy copies and dd deletes only one line, without duplicating or removing the line below.
