I find it unfortunate you think about it like this:

1. true, but reasoning like this there would be no video anyway
2. irrelevant, it's a feature, doesn't matter how popular it is
3. they do, the behavior described is not the intention so it is not a choice to interpret the markdown like this, if you look at the code it is clear the intention is not to do this, so that makes it a bug

Even if it were not a bug it would make for a good suggestion.

I contacted @fabien about this and he considered it a bug and added it:
