IndexSizeError in Chrome

steps to reproduce

Using empty editor instance on summernote.org which currently has v0.8.1 of summernote.js

If I do the following: <kbd>a</kbd> -> <kbd>SPACE</kbd> - > <kbd>CTRL</kbd> + <kbd>b</kbd> -> <kbd>SPACE</kbd> (code view shows <p>a <b>&nbsp;</b></p> in Chrome at this point)

I get this error:

Uncaught IndexSizeError: Failed to execute 'setStart' on 'Range': 
The offset 2 is larger than or equal to the node's length (1).

There is a similar error in Microsoft Edge; Firefox is unaffected. I do see that the generated HTML is slightly different in each case.

If I do the following: <kbd>CTRL</kbd> + <kbd>b</kbd> -> <kbd>a</kbd> -> <kbd>a</kbd> -> <kbd>CTRL</kbd> + <kbd>b</kbd> -> <kbd>SPACE</kbd> (code view shows <p><b>aa</b>&nbsp;</p> in Chrome at this point)

I get this error:

Uncaught IndexSizeError: Failed to execute 'setEnd' on 'Range': 
The offset 2 is larger than or equal to the node's length (1).

I see this error only in Chrome.

browser version and os version

Reproducing @balramkhichar 's instructions from above on the official https://summernote.org/ instance shows the issue isn’t yet fixed (and the removeModule trick from above doesn’t seem to have any impact either).
