I was surprised there is no scrollbar but I have checked it in standard Firefox and scroll bar is there. Perhaps there is something wrong with the ESR version.

As for the "It cannot see the all paragraphs". Please not that zoom is only assigned to editor content area and not main page.

Similar zoom plugn issue was also mentioned here: #13372

Thanks for your answer j.swiderski. The scroll bar is set to hide when plugin Auto Grow is enabled. This is correct as you can see in ​http://ckeditor.com/demo#auto-grow. But when Auto Grow plugin and Zoom plugin are enabled together and zoom level is set above 100%, the autogrow doesn't work as it should. In Chrome 46.0.2490.86 and Firefox 42.0, after to apply zoom 125%, for example and to click into editor's editable area, the editable area does not grow enough to make the entire text visible in the editable area. In Internet Explorer 10.0.9200.17357 the autogrow plugin makes the editable area grow enough after zoom 125% (or above), but only just after the click into area editable.

@edsonperotoni thank you for the follow up. Yes, you are right. There is no scroll and you can't see the whole text. I must have not checked this properly.

The problem is that zoom plugin is third-party plugin and we don't support it. I'm confirming this issue because maybe the autogrow could (as well as find plugin from #13372) support the transform: scale(N.NN);.
