Wrong behaviour for Enter with multiple instances.

[Francisco]

If there is more than 1 instance of CKeditor and I press enter in the second or consecutive ones, the whole page moves down. It doesn't happen when I only have one, but it happens both with the _samples example (second one) and when I use the code for my pages. Couldn't test it in the Demo from the page since there's only one instance. It's a fresh install with no plugins.

Steps to reproduce:

1. Go to the /ckeditor/_samples/replacebycode.html , but don't get in the bottom of the page (so you can see the effect).
2. Write some text.
3. Press Enter.
4. The line break get's printed in the textarea and the whole page moves down a lot. I'd say same thing as 'Page Down'.

I have checked replacebycode.html sample and this issue does not occur there.

I have then checked your page and IMO this scrolling happens because you have invalid page structure. The main error is having nested html tags. I don't remember this being valid in HTML5 or any HTML spec ;)

Please see link from validator - ​http://html5.validator.nu/?doc=http%3A%2F%2Fnewfutureuniversity.org%2Fckeditor%2F_samples%2Freplacebycode.html
It should give you an idea what should be fixed.

I should have modify the page itself (it auto-loads a lot of code) for the bug, I apologize for that.

Here you can see a page that validates perfectly with HTML5, not even a warning, but still suffers the same problem as explained in the first post: ​http://newfutureuniversity.org/test/wiki/

Can you point somewhere that I can test if it's my browser's problem or a general bug please?

Hi @Frank91, sorry for late response.

Your ticket is in fact a duplicate of #9136.

You problem is CSS rule set for body - height:100%. Please change it to height:auto and problem will be gone.

[Francisco]

No worries,

Oh I didn't find that before. If I change it to auto, the bug 'gets fixed' but my page breaks at some points (the sticky footer stops being sticky). Is there any other workaround? I've seen on the other post that older versions of CKeditor didn't have this problem.

Anyway, thank you for taking the time to answer.

This is a little bit out of scope of bug reporting but here goes:

1. In sample.css you have rule set for body padding: 10px 30px;
2. you should change it to padding: 10px 30px 0;
