[dhananjay1405]

Whenever any HTML tag is selected, and cursor is moved using shift plus left/right key, a mirror selection of text happens in editor from position where it finds HTML end tag, thereby selecting non-continuous region

Having the same issue:

Shift+End:

Shift+Arrow:

Which will cause a mild rage after hitting delete in such a situation when the end tag is not visible

Until this and #87067 aren't fixed, I'm turning off this feature

This is a feature called "Mirror Cursor", which adds a multi-cursor when you are inside a HTML tag, and this is the expected behavior of multi-cusor.

You can turn this feature off by `"html.mirrorCursorOnMatchingTag": false" or press ESC to dismiss the multi-cursor before selection.

Or you can wait for implementing #88424 which will duplicate content changes, but not selection.
