However it does seem to take a "long" time for the icon to appear. From clicking "install" in the browser to icon appearance can take roughly 1 minute. This may or may not be reasonable - a lot is happening, the package is being downloaded and installed, various IPC calls for installation and acknowledgement etc, this is also being tested in a VM.
I am not able to replicate this.
