Text style lost on previous line in enterMode = CKEDITOR.ENTER_BR when deselecting the style in the toolbar

[pauljvrw]

How to reproduce:

• 1 - Go to ​http://nightly.ckeditor.com/
• 2 - Choose the sample "Using the "Enter" key in CKEditor"
• 3 - Choose the 'use <BR> when enter is pressed' setting.
• 4 - select 'underline' in the toolbar and type some words.
• 5 - Type enter for going to a new line
• 6 - deselect 'underline' in the toolbar

Now all underlining is removed from the previous line. The bold and other styles have the same problem.

In paragraph mode this does not happen. Same if you do not go to a new line. Therefore expected: text style on previous line is preserved after an enter in BR mode and subsequent deselect of the style in the toolbar.

Browsers tested: FF: bug found Safari: bug found Chrome: bug found IE9: Works as expected IE8: Works as expected

Should have been

Now the added underlining is removed from the previous line.

Reproducible in Firefox, Webkit IE10 and Opera (IE6-9 works fine) from CKEditor 3.6.3 rev. [7392].

This TC can be applied to all format buttons as well as inline styles from Styles Dropdown.

NOTES:

1. From CKE 3.1.1 till CKE 3.6.3 rev. [7392] it was not possible to remove underline. Disabling underline (point 6 of the TC) seemed to work but typed letters still appeared with underline.
2. Opera has its problems with jumping cursor #6585 but the problem occurs there as well.

It seems we have few more tickets caused by this revision: #9933, #8980, #8942.

#9933 is in fact a duplicate of this issue. Problem concerns all inline styles.

#10435 was marked as duplicate.

Problem can be reproduced in both CKE 3.x and 4.x branches.
