Thank you for indulging my silly word fetish. What is the state of affairs that could be identified as deliberately or merely accidentally/incidentally contrary in this situation:

  * There is a discussion of a problem in V8. 
  * While reading the discussion a user stumbles across a problem in Chrome. 
  * V8 is a component of Chrome.
  * The Chrome bug may or may not be related to V8.

For the sake of the discussion we can pretend that "deliberate" is not a key component of the definition you give[1] and substitute incidental/accidental. What is the contrary result? Given the memory leak in V8 we know that V8 is not the first software product to be bug free. So it should not be surprising or unexpected that there may be another problem in V8 or Chrome.

One of the things that I find interesting about the way irony is tossed around these days is that it signals no information. As a result it is never an "entirely wrong word." Because it does not convey anything to the reader it is merely superfluous. Ironically and randomly have become linguistic NOP sleds.

[1] I have no problem with your definition and I realize you were not endorsing OP's conception of irony.
