[Bug] Typing to replace a multi block selection does not clear the entire selection

Create a multi block document:

```
a
b
c
```

Select all blocks. Now press any key (for example "d"). The block that was last interacted with will remain on the screen, so the document will now look like this if c was the last block interacted with:

```
c
d
```
