Changes between Initial Version and Version 1 of Ticket #12621, comment 2

initial	v1
1	1	It might look like a regression, but actually it's not. It's an older bug in the styles system (I might have reported it some time ago).
2	2
3		On 4.4.4 (an earlier versions), when you do that TC, there is an empty inline element left after you press the style keystroke for the 2nd time - `<p><strong></strong><br></p>`. It should be removed by the styles system when removing the style, but it's not.

5	5	In 4.4.5 in #12423 we changed a behaviour of a method important for the styles and selection systems (so it's hard to say what it could affect). And I think that this change might actually be good, because it aligned the method behaviour on Webkit/Blink to Firefox. And on Firefox this problems isn't reproducible. This may mean that there's some other part of code wrong on Chrome/Blink (e.g. the code that affects the getStartElement() method).
