CKeditor 3.2.1. links font size changes when deleting the lines on top only seen with FireFox.

How to reproduce this problem:

• paste the html source code in CKeditor textarea (html source provided below)
• put the cursor right before the link "Forward this to a friend" (at the beginning of the line).
• select the line above ("also this last ...") with the up arrow key.
• delete the line you just selected
• Notice how the link font looks bigger

Below is the html source to test with

Firefox doesn't preserve block styles when merging blocks on 'Backspace', we can do nothing to the bug at the moment because having no managed 'Backspace' implementation.

It's not a bug. It is an expected behaviour. Browser should only consider semantic as important, because when it starts thinking about styles it is making awful mess, like Webkit and Blink do in #9998.
