Code line resets to 'p' element

[fbolcic]

Hello,

We added a code block plugin with a custom component. We see that children (lines) of the code block are of type code_line. The problem is, when we try to delete a line the code_line element is reset to p, which messes up with our formatting. We would like to delete the whole code line in this case, not convert it.

Moreover, we cannot delete the line with backspace when it is set to the p element, we can only do it with control+backspace. When it is the first line of the code block not even control+backspace helps, which means we cannot delete the whole code block.
Attached below is a video of the behaviour:

We would like to:

1. stop converting code lines to p element. When we use backspace on an empty code line we want to delete it, not convert it to p.
2. exit the whole code block if we are using backspace and there is only one empty code line.
