It took me a while to figure it out, but finally I found the root of the problem, precisely those mysterious lines in toolbar.css and a bug in IE11 which makes background-image blurry when border-radius is set (sic!).
At first I was not able to reveal the mystery of that RTL-specific CSS because git blame is useless in this case. It looked like a dead piece code for me. Eventually I figured out that those rules are to make a.cke_button rounded if it's the first/last child of .cke_toolgroup. Without those CSS, .cke_toolgroup's border, which is also rounded, would be distorted by children.
However, the selector .cke_rtl .cke_toolgroup *:(first|last)-child is greedy: it also selects .cke_button_icon which is the first-child of .cke_button (IE11 "blur-bug" kicks in). Additionally, for unknown reason, the rule existed for RTL editors only while the issue (distorted .cke_toolgroup's border) is also visible in LTR.
I created branch t/11542 which does the following:
- Fixes the greedy selector (the blur is gone).
- Applies the fix to LTR editors.
