Solves #243

This has been an irritating issue that I've been facing, the issue seems to describe it quite well.
Please let me know if you have any comments :)

@hramezani @Linkid can I get an update regarding this please? I cannot request a review on the PR.
Just in case if there is anything blocking from my side, or if there is a decision that this bug is not relevant.
