Use of <End> key on a line in insert mode and subsequent left arrow key misfires

Describe the bug
Using End in insert mode on a line, and then using the left arrow key in the hope of moving back one character does not work. It seems to apply the left to the cursor location before the jump to End using the End key.

To Reproduce
Steps to reproduce the behavior:

Have any document with a long line of text. From the middle of the line, press end. As expected this takes you to the end of that line. Now, pressing left arrow key does not take you to one character left on the line from the end position. Rather it takes you back one character to the left of your original cursor position you were in before executing the End to reach the end of line.

Please see screencast below.

Expected behavior
From the end, pressing left, or right should use that position as the relative position from which to apply left or right.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.26.0
• VSCode version: 1.74.3
• OS: Linux Ubuntu 2020 LTS

Additional context
The extension related settings in settings.json are:

    "vim.handleKeys": {
        "<C-a>": false,//vscode, this selects all.
        "<C-b>": false,//vscode, this toggles sidebar

The contents of my .vimrc of vim.vimrc.path in settings.json is:

set hlsearch

set smartcase " if searched with upper case, preserves. Else, ignores case
set incsearch " incremental search
set number relativenumber

inoremap jk <ESC>

Start by reproducing the End-then-left and End-then-right sequences in VS Code using the reported insert-mode setup, including the listed key mappings and Neovim settings. Trace the extension's handling of End and arrow keys; done means subsequent left or right movement starts from the line end rather than the cursor position before End.
