If text is both code and italic, unclicking code has no effect

[rbohrer]

Goes without saying this is a lower priority one.
Repro:
Type a word like "hello"
Highlight hello
click the code button
(highlight again if needed and) click the italic button, note it becomes italic code
click the code button a second time, note it does not change
For contrast:
Now highlight and click italic again, it will un-italic
Now highlight and click code again, it will un-code once it has been un-italicized
