IE: Pasted block content into an inline style creates invalid HTML

[Teresa Monahan]

To Reproduce:

• Open any CKEditor 3.x sample in IE and clear the contents.
• Type some text and use Ctrl+A to select it.
• Use Ctrl+C and then apply a font-size to the selected content.
• Place the cursor at the end of the content and press enter.
• Paste the content using Ctrl+V.
• Place the cursor anywhere in the pasted content.

Problem: The element paths bar displays body span p. If you inspect this content using developer tools you can see that the pasted paragraph is a child element of the span with the font-size styling.

The editor corrects this when you switch to source mode and back or save the content. However this has a direct impact on users if they have specified a font-size style for p elements in contents.css - see attached screen capture.

This is a customer reported issue. It seems related to ticket #8294. I cannot reproduce it in CKEditor 4.1.

@tmonahan this is another TC for same problem. We have 3 tickets for this problem defined - #9207, #8294 and #8736. They all have same cause.

I'm closing this as duplicate of #9207 although it doesn't matter which ticket I select. They all have the same fix.
