Chrome exports corrupted .tgz file while Firefox doesn't (HANA sp8)

Today I discovered that the a Delivery Unit archive file exported from browser based ALM UI is corrupted.

This always happen when I use Chrome browser. This doesn't happens on FireFox browser.  Share with you so that you don't have to spent too time on this issue.

Is this a bug in the browser side javascript code in /sap/hana/xs/lm package?

The archive file has a .tgz extension.

Here's the error in the ALM browser UI when I tried to import the .tgz in question.
