Parchment Error thrown when trying to replace text that includes formatting and newlines

[clemmy]

When I have editor content that includes bolds and new lines, and I highlight all the text (via cursor or Control + A), then I press a key in order to replace the text, Quill throws an error, ParchmentError: [Parchment] Unable to create [object HTMLElement] blot. The stack trace is as follows:

create (quill.js:929)
(anonymous function) (quill.js:568)
ContainerBlot.update (quill.js:561)
FormatBlot.update (quill.js:1084)
(anonymous function) (quill.js:1503)
ScrollBlot.update (quill.js:1500)

Steps for Reproduction

1. Visit http://beta.quilljs.com/playground/

2. Paste the following into the editor.

   asdf

   asdf

3. Select all the text (with cursor or by pressing Control + A)

4. Press a key (e.g. 'x') in order to replace the selected text

5. Observe that the error is thrown.

Expected behavior:
The selected text should be replaced with whatever you type.

Upon further analysis, it looks like query(input) is returning a Text element inside Firefox (where the behaviour is correct). However, query(input) is returning <b>X</b> in Chrome, which leads to a logic path that throws an error.
