Pasting HTML into inline editor clones the element

[infosaurus]

I have the following inline editable element :

<h2 class="editable-simple mce-content-body" id="title" style="position: relative;" contenteditable="true" spellcheck="false" data-postback="Title">title</h2>

initialized with

        tinymce.init({
            selector: '.editable-simple',
            inline: true,
            toolbar: 'undo redo',
            menubar: false,
            plugins: "paste",
            paste_as_text: true
        });

In Internet Explorer, when I copy a heading from somewhere else (either a h1, h2, etc. from a web page or a heading from Word) and paste it in that editor, the <h2> element is duplicated. In other words, a second <h2> is added to the DOM and appears besides the normal one. It is editable but blank (doesn't contain pasted text) and has the same ID and attributes as the real one.

Sometimes, for instance when I repeatedly paste the heading in the editor, the same thing occurs but the inserted h2 is non-editable and contains pasted text.

paste_as_text: true is an attempt to go around that problem by preventing formatted text to be pasted, but doesn't solve anything.

Thanks for your help.

TinyMCE 4.5.1

Hi! Can you reproduce the issue in a fiddle to make it easier for us to understand the problem?

Hi fyrkant,

I reproduced the issue in fiddle.tinymce.com by just inserting the code from my first message and copy pasting in the inline editor a h1 from any web page, say a Wikipedia article for instance.

http://fiddle.tinymce.com/VJfaab on IE11

Repeating the code here, just for reference :

<script type="text/javascript">
        tinymce.init({
            selector: '.editable-simple',
            inline: true,
            toolbar: 'undo redo',
            menubar: false,
            plugins: "paste",
            paste_as_text: true
        });
</script>

<h2 class="editable-simple mce-content-body" id="title" style="position: relative;" contenteditable="true" spellcheck="false" data-postback="Title"></h2>

Hi,
I'm unable to reproduce this issue in TinyMCE 4.9.10 and 5.2.2 using the details provided, however looking back at the changelog it appears this issue was fixed in TinyMCE 4.7.12. As such I'm going to close this, however if you're still experiencing issues then let us know and we'll reopen this issue.
Thanks!
