@yukiisbored I'm a newcomer and just opened a PR in this repo. Just wanted to know if there's any progress on this.

@manankalra Hey, very little progress is made due to time constraints. I'm gonna unassign myself from this.

[manankalra]

@yukiisbored I can take this issue if you can guide me a little on what needs to be done. :)

I want to try and fix this... can you assign this to me? @yukiisbored

#51 is likely to be helpful to find and fix this bug.
