Bug

Provide detailed reproduction steps (if any)

1. Type a space between two words somewhere in the middle of a sentence:
   <h1>Hello| world!</h1> -> <h1>Hello | world!</h1> - the caret becomes between two spaces.
2. Press backspace to delete one space on the left.
3. Type a space and new word "foobar".

Expected result

<h1>Hello foobar world!</h1>

Actual result

<h1>Hello foobar&nbsp;world!</h1>

I wonder what is the impact of this issue, @nag5000 could you elaborate on the problems it causes for you?

Any input from other people upvoting this issue is more than welcome too. It will help us to understand better what are the cases here and what will be the best solution (and what parts of the editing/outputing process it should involve).

@f1ames Writing blog posts, leaving comments... almost any case where ckeditor can be used. If the output is html with a lot of non-breaking spaces, it will not be rendered correctly to the end-user.

I faced this issue intermittently when updating lengthy content. Backspace and space keys are used frequently. Because of   the line breaks. It is difficult to solve if source button is disabled.

Is this related to https://www.drupal.org/project/ckeditor_details/issues/3159925?

For now, I see that:

1. Putting extra space before existing space gives us  space combination for Chrome and FF.
2. Visually we have caret between two spaces.
3. When we delete first or second visual spaces (backspace or delete):
   
   
   
   • for chrome gives us only  
   
   
   • for FF gives us space
   
   

The same for wysiwygarea and divarea

Also bugged in IE11 - However, it works that way even in plain contenteditable - without CKEditor.
