While the entity gets loaded, we show a very rudimentary "Loading..." text so signal to the user that bridge is still trying to gather all data needed to operate.
We probably want to make this more appealing than it currently is.
- the loading indicator always has a minimum screentime of 0.5 seconds
- The fade in starts after 1 second
- look and feel of OOUI Progress bar (indeterminate)
- might add a fade in and out later
