Can't open links that has hashbangs(#!)

[dogancelik]

When I try to open this I can't: http://twitter.com/#!/SomeUsername

When I click somewhere after # (a position after #) and do link:open, I can't open link.

When I click somewhere before # and do link:open, it opens link incorrectly: http://twitter.com/ without including after #

2nd example: https://github.com/#asd/qwe → https://github.com/#asd/qwe (Works!)
3rd example: https://github.com/#!asd/qwe → https://github.com/ (Nope!)
4th example: https://github.com/asd/qwe#asd → https://github.com/asd/qwe#asd (Works!)

Edit: I'm using Atom v0.194, Win7 64-bit

Confirmed on Ubuntu 15.04, latest master.
Seems like link stops recognizing that it's still a valid URL after the !
