VSCodeVim blocks VS Code's native handling of Tab and Escape

Currently setting tab in vim.handleKeys does nothing

    "vim.handleKeys": {
        "<tab>": false,
    }

Describe the solution you'd like

Since tab is frequently used by other extensions and VS Code itself it would be helpful to allow the native handling to happen from VSCodeVim.

Similarly, escape is also used for many native affordances. Since escape in normal mode isn't typically mapped to anything it would be helpful if VSCodeVim could allow native handling of esc when in normal mode.

A clear and concise description of what you want to happen.

Describe alternatives you've considered

Attempted to change settings and keybindings, but couldn't get anything to work.

It's worth noting perhaps that in insert mode <tab> works well with other extensions and VS Code since VSCodeVim doesn't intercept it.
