Background processing
~~~~~~~~~~~~~~~~~~~~~
The project will be paused by the browser when the tab is no longer the active
tab in the user's browser. This means functions such as ``_process()`` and
``_physics_process()`` will no longer run until the tab is made active again by
the user (by switching back to the tab). This can cause networked games to
disconnect if the user switches tabs for a long duration.

user's side, this can be worked around by running the project in a separate
*window* instead of a separate tab.
