13924	IE11 - Typing is slow after pasting for the second time into editor.	Jakub Ś	Tomasz Jakut	"== Steps to reproduce ==

1. Open attached 27 page document and paste it into editor.
2. Start typing immediately after paste. Document is being still processed so first characters my not show up **but later on you can type without problems**
3. Press Ctrl+A and Backspace (you can press delete and backspace few times - it doesn't matter)
4. Paste text again and again after the text shows up start typing.
Actually you can wait few seconds and then start typing.

== Expected result ==

Typing speed should be normal.

== Actual result ==

Typing is very slow even after few minutes.


== Other details (browser, OS, CKEditor version, installed plugins) ==

Problem can be reproduced in IE11 only. IE11 is supported from CKEditor 4.3 but I have seen this issue even in CKEditor 4.0.
