Search plugin doesn't scroll properly when there is only "BR content" in editor

[Thomas Nickl]

Steps to reproduce:

• mkdir ckeditor-bug
• cd ckeditor-bug
• wget ​http://download.cksource.com/CKEditor/CKEditor/CKEditor%204.2.2ckeditor_4.2.2_full.zip
• unzip ckeditor_4.2.2_full.zip
• Copy test.html from this ticket's attachment to here
• Call up test.html in a browser
• Click magnifying glass in toolbar to call up search.
• Enter xxx into search box
• Click "Search" button multiple times. xxx occurs twice in the text, at the beginning and in the middle. The cursor jumps around to the start and end of the text without ever showing the second occurance of xxx.

Edit:

1. Put code from attached file in to editor.
2. You can also write your own content but editor needs to be set to enter mode BR.
3. Try to find 'xxx' or whatever word there is in your text and repeats throughout the content (there has to be few pages of content).

Result: Editor will match and select word but will not scroll to it correctly (This can be checked when you resize editor to match whole content).

Problem can be reproduced in all browsers from CKEditor 3.4
