Spaces inside <code> should be rendered in a normal way

[Reinmar]

We assumed that subsequent spaces must be rendered in "as is" way in <code> elements, without encoding them to pairs of "space + nbsp". However, this isn't correct, as we learned in ckeditor/ckeditor5-basic-styles#55 (comment).

Maybe it will let us skip looking backward in space-replace algorithm.

[Reinmar]

It has nothing to do with that. We just need to remove code from the preElements array which introduces special behaviour for them.

Exactly... apart from styling, I don't see much difference between code and strong, for example.

Well, we look back because we assumed that there are elements in which we don't want to convert spaces to  s. <code> was supposed to be such an element. If this is not a case, then why should we look back?

If this is not a case, then why should we look back?

You might be right that we don't need to look back if we'd assume that previous text node's last space is always converted to nbsp, but this is not related to the <code> stuff. We assumed that spaces inside <code> are preformatted anyway, so that they behave like nbsps.

Okay I won't argue because I don't remember that algorithm and all the cases precisely.
