No backspace can be used after EOL.

## Information

**VIM version**

8.1.1244

Operating System:
Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04
Codename: bionic

## What went wrong

I disabled all plugins. When I try to go to the new line and use backspace it doesn't work.

## Reproducing the bug

1. Save file as `*.js` with this content:

```
const whatever = {
key: 1,
}
```

2. Go to edit mode. By having cursor at the end of this line `key: 1,`.
3. Use enter.
4. Try to use backspace to go to the beginning of the line you currently are.
5. No results. I could be possible when exit edit mode.
