While in insert mode, pressing the end key and then the left arrow key makes the cursor jump to a wrong position.

Describe the bug
Using the left arrow key after pressing END in insert mode makes the cursor move two characters to the left instead of one every other time. Sometimes it jumps to even further left, but I do not have a way to reproduce it reliably.

To Reproduce
Steps to reproduce the behavior:

1. Enter insert mode and
2. Press the end key to go the end of the line
3. Press the left arrow key
4. Cursor goes two characters to the left instead of one.
5. Repeatedly press the end and left arrow key to see that the bug happens every other time.

Expected behavior
Cursor goes one character to the left every time the left arrow key is pressed.

The end key seems to only trigger "Changing Cursors from selection handler" every other time. When that is triggered, the cursor moves correctly on the next left arrow key press. If it doesn't, the cursor jumps two characters instead.

Environment:

• Extension (VsCodeVim) version: v1.26.0
• VSCode version: 1.82.0
• OS: Windows 11

Reproduce the issue in VS Code using insert mode, alternating the End and left-arrow keys as described. Start by tracing the selection-handler and cursor-change behavior shown in the debug output; done means the left arrow moves the cursor exactly one character left after every End press.
