BUT I went back to it (IE11/Win7) and lo and behold I see that too. HOWEVER if anyone from IB is reading, the quote icon function DOES work of you select the code page on the editor (a/A top right) and the quote tags do appear (as do all the smilies). If you then post the relevant text between the tags/with the smilies and then return to normal ed mode it looks ok.
I'm logged in using gargle chrome to see if these functions work here.
Yes they do
