It's because the GUI creates a "WebTimer", not a "Timer".

"Timer" ticks internally in the session server process, and can't force 
an update of the web browser client, whereas "WebTimer" ticks in the 
client web browser, and then can update the interface.

The update of the web page can only be done in a response to a request. 
It cannot be forced from the server if a request has not been initiated 
from the web browser, i.e. from a GUI event (bouton click, WebTimer 
tick...).
