br tags are removed when switching to source an back.

[Jakub Ś]

This is the continuation of #10146 issue.

Problems can be reproduced in all browsers and don't occur in CKEditor 3.x

Examples:

---

Two brs are handled the same way as one br

Both code snippets

<br>
<br>
<p>This is a paragraph of text.</p>

and

<br>
<p>This is a paragraph of text.</p>

will result into:

 
<p>This is a paragraph of text.</p>

---

This

    <br /> 
    <br /> 
    <p>This is a paragraph of text.</p> 
    <br /> 
    <br /> 
    <p>Second paragraph of text.</p>

results in

 
<p>This is a paragraph of text.</p>
&nbsp;

<p>Second paragraph of text.</p>

---

One br is chnaged into  

This

<table>
	<tbody>
		<tr>
			<td>Table cell contents</td>
		</tr>
	</tbody>
</table>
<br>
<p>P contents</p>

will result in

<table>
	<tbody>
		<tr>
			<td>Table cell contents</td>
		</tr>
	</tbody>
</table>
&nbsp;
<p>P contents</p>

I understand that fix for #10146 has introduced fix which changes last BR into &nbsp and most likely example two is a "won't fix". Another reason for this may be that nbsp; in second example creates in fact new line.
The only problem with example two I see is that code is in fact different to what user has entered and this doesn't occur in CKE 3.x.

Example one is rather a bug and there should be some difference between how one and two BRs are handled.

EDIT: This ticket is the follow up to #10146. Most scenarios from #10146 were fixed. Examples mentioned in this ticket are still live. When fixing this issue, please have older test cases from #10146 in mind so that they didn't get broken again.

There is a workaround mentioned in ​http://dev.ckeditor.com/ticket/10146#comment:34. It actually handles all the cases but one. When there is no other way to fix it perhaps some smarter way of using that hack could be implemented?

Other issues that seem to be related to this one: #10431, #10497, #12209.

#13458 was marked as duplicate.

Perhaps methods mentioned in ​http://dev.ckeditor.com/ticket/10146#comment:21 could be changed to handle these cases.

Hello, Can you please let us know when would a fix be provided for this issue?

[Jakub Ś]

@sudeepvs have you tried workaround mentioned in ​http://dev.ckeditor.com/ticket/10146#comment:34? From what I have checked it works for all the cases but one.

Let's see what we can do about it.
