Format issues if only a single word is typed (Edge browser)

[G-S2h]

hi, and thank you for your great WYSIWYG,

There is a bug with Edge browser where format actions (such as bold) result in an Unable to get property 'textContent' of undefined or null reference if one tries to format the word he has just typed.

Steps to reproduce:

1. Make sure all SunEditor textarea is empty;
2. Type a word; select this word and apply some basic format (bold e.g.) to it.

If you do not type anything and first click a format option, it will break a new formated line in textarea, but (plus) it may lead to a new bug.

Steps to reproduce:

1. Make sure all SunEditor textarea is empty;
2. Click on Bold (cursor should move below) then type a first word;
3. Click back to Bold, hit and space a type another word;
4. Select that second word and click on Italic.

But it works with keyboard shortcuts

However I have noticed that everything works well if you use keyboard shortcuts, even if the error logs in console (Unable to get property 'textContent' of undefined or null reference).

Thanks for your reporting.!

The old version of the edge browser is really hard.
Even "selection" has different results than IE. :(
I modified it, but it may not be perfect.

I'll notify you know after version update.
