UI does not detect the end of the installation of a binding

[lolodomo]

The problem

When you request the installation of a binding from Main UI by clicking on the INSTALL button, UI replaces the button by a circle that shows that installation is in progress. The problem is that it never ends even when the bundle is fully installed.
Main UI seems to not detect the end of the installation.

Finally, if I reopen the page, the binding is shown as installed.

Expected behavior

Main UI should detect the end of the installation and show the UNINSTALL button instead of the "in progress" circle.

Steps to reproduce

Try to install any binding.

Your environment

I am using Firefox. I did not test if this is specific to Firefox but I doubt.

I can confirm that this is also happening in Chrome and therefore not browser related (IMHO).
