Admin authentication prompt not shown first time Install is clicked

[Wes]

To reproduce:

As a standard non-admin user, download Google Chrome .deb file and open it with software install.
Click the Install button

Expected:
Authenticate prompt for administrator password, and proceeds with installation on clicking install the first time.

Actual:
Nothing happens, orange progress seen on button, but no admin prompt first time. Have to click install a second time after this for the admin prompt to be displayed.

Thank you for your bug report. Do you get the issue every time? Is that specific to chrome or does it do it with other debs as well?

@seb128 Happened almost every time. Also observed with other debs such as https://atom.io/download/deb
