when do you "undo" these changes to hidden and textContent? eg, if I open the
site in another tab and it adds cookies, i'd expect the container to be shown

[Finnur, 2016/07/07 10:54:01]

So... The list of data stored by the website is mostly static, meaning: you'd
have to refresh the page to see changes. The exception is when cookies are
deleted -- that's reflected right away (it would be really weird if it didn't).

The reason the list is static is mostly down to priorities and time remaining:
a) The CL had gotten large and complex enough to review without also including
dynamic updating for when cookies are added.
b) If the CL were larger I wouldn't have been able to complete the CL in time
for my vacation.
c) Dynamically updating is probably lower priority than some of the other Site
Settings things that need to happen for this to launch (e.g. the categories for
USB, protocol handlers and Zoom are currently missing).

Acknowledged. Could you please open a separate bug to track this?

The bug for the missing settings is here: http://crbug.com/614277
The new bug for dynamically updating the Cookie Data list is here:
